Update the custom vector table to have timer2_isr that
is used for kernel system timer.
While test passes test immediate crashes afterwards due to
missing handler for non-SysTick interrupt.
Now custom interrupt table has additional interrupt handler
to prevent crash.
timer2_isr is no longer static that should not result in
any conflict.

The MCP2515 driver can be configured with 1, 2, or 3 transmit
buffers via the `MCP2515_TX_CNT` constant.
The interrupt handler checks for transmit complete interrupts for
`TXB1` and `TXB2`. However, the code for these checks was not guarded
by preprocessor conditionals. This meant the code would be compiled
even if the driver was configured to use only one transmit buffer
(`MCP2515_TX_CNT=1`), which is the default.
This change adds the appropriate `#if MCP2515_TX_CNT > 1` and
`#if MCP2515_TX_CNT > 2` guards around the interrupt handling logic
for the second and third transmit buffers, respectively. This ensures
that the code is only included when the corresponding buffers are
actually configured, improving code clarity and preventing compilation
of unused logic.

Speed up execution of the interrupt handler and sys_clock_set_timeout().
Sys_clock_set_timeout() can be called in two scenarios: from previous
timeout expiration handler or freely. If the former case fast path
can be used since CC value in the GRTC register just expired and it
can be used as a reference for CCADD setting. This is only a single
register write so it's much faster. In the latter a longer procedure
is applied which also happens in two variants. If value which is
set in CC is further in the future (e.g. K_FOREVER was set before) then
CC can be safely overwritten with a new value without a risk of
triggering unexpected COMPARE event. If value in CC is earlier than
the new CC value (if earlier timeout was aborted) then there is a
risk of COMPARE event happening while it is being overwritten.
That case requires long and safer procedure of setting CC.

When system was configured to use smartbond_timer with
tick-based kernel, timer interrupt could fire only
once and then time would not advance.
Now when tick-based kernel is chosen timer2_isr()
schedules that it should be fired at next tick.
Timer comparator calculation code was extracted
from existing sys_clock_set_timeout() function
without change so it can be used for tick-less
and tick-based kernel.

Remove the node syspll2x refering to the output of SYSPLL CLK2X.
SYSPLLCLK2X is controlled via the clk-div2x parameter of the SYSPLL
DT node and only CLK2X or CLK0 can be activated. So there is no need
for an additional node, as routing of downstream clocks from SYSPLL
CLK0/CLK2X are defined by which of the two is active.

According to the TI MSPM0 reference manual MDIV must not be set if
SYSOSC is not configured to 4MHz. To make use of this setting, it is
necessary to enable configuring the SYSOSC clock of either 32MHz
(default) or 4MHz with the clock-frequency parameter of the
sysosc node.
If the SYSOSC is configured to run at 4MHz, then the MCLK divider
setting is applied.

Add bus idle wait after clock rate query to ensure AHB transactions
complete before device configuration. This prevents XSPI_SetDeviceConfig

transactions that complete asynchronously, causings subsequent device
configuration to fail due to its bus status checking.

Add mode to be used on UARTE with frame timeout which is using a bounce
buffers and TIMER to count bytes. This mode shall be used to reliably
receive data without HWFC as frame timeout approach is not 100% reliable
because it can loose or corrupt a byte when new byte arrives after
frame timeout is detected but before it is fully handled. This mode is
similar to the one enabled with CONFIG_UART_x_NRF_HW_ASYNC but
additional bounce buffers are used and UARTE is receiving data to
internal buffers and copies data to the user buffer. Legacy apporach
cannot be used because in new SoC DMA attempts to copy data in words
so when byte is received it stays in the DMA internal buffer until
4 bytes are received or end of transfer happens then internal DMA
buffer is flushed.

Configure the link status in the Link Status Control register for
LAN8670/1/2 Rev.D0 PHYs, depending on whether PLCA or CSMA/CD mode
is enabled. When PLCA is enabled, the link status reflects the PLCA
status. When PLCA is disabled (CSMA/CD mode), the PHY does not support
autonegotiation, so the link status is forced active by setting
the LINK_STATUS_SEMAPHORE bit.
The link status control is configured:
- During PHY initialization, for default CSMA/CD mode.
- Whenever PLCA configuration is updated.
This ensures correct link reporting and consistent behavior for
LAN867x Rev.D0 devices.
