As mentioned in the i2c_burst_write documentation, this API may not be
supported by all I2C devices. The recommendation from this documentation
is to use i2c_write with a buffer containing the combined address and
data.
The ssd1306 driver was working well when using I2C but not when using
I2C over I3C. In this case, the control command was sent in a separate
transaction, which the SSD1306 does not support. To fix this issue, we
should apply the recommended approach and use i2c_write instead of
i2c_burst_write. The solution implemented uses chunks to avoid stack
overflow when using large buffers (it can be up to 1 kB).

This fix adds a macro for writing register updates in big endian
at compile-time to fix an issue with multi-device configurations.
Previously, the I2C write function would flip the byte order of
arrays unconditionally, which is problematic if arrays are shared
across instances of a driver. Adds a new "raw write" for I2C
transactions where the uint32_t array to write is already in BE32
format.

The initial driver implementation used ring buffers, kept a private
variable to count "effects in flight", and register GPIO callbacks
to log playback events, but these ultimately bloat the driver and
introduce new issues where a dropped start or complete playback can
force the driver into a bad state. Additionally, the mailbox events
already provide sufficient log information if needed. As a result,
let's simplify the driver's logging mechanisms.

The custom arm_arch_timer arch_busy_wait() computed the wait duration as:
cycles_to_wait = sys_clock_hw_cycles_per_sec() / USEC_PER_SEC *
(uint64_t)usec_to_wait;
Integer division applied first. When the timer frequency is not an
integer multiple of USEC_PER_SEC (e.g. 62.5 MHz on Cortex-A53), the
fractional cycles-per-microsecond are silently dropped, making every
call to k_busy_wait() return short by up to 0.8% of the requested
duration -- breaking the API contract that busy_wait() is guaranteed
to wait at least the requested number of microseconds.
Replace the open-coded conversion with k_us_to_cyc_ceil64(), which
multiplies first and rounds up, so the resulting cycle count always
covers at least the requested microseconds.

Introduce a PECI transport driver that operates over the eSPI bus,
enabling platforms without a native PECI controller to communicate
with the host CPU via an embedded controller.
This driver:
- Implements the PECI transaction layer on top of eSPI OOB channel
- Serializes PECI transactions to ensure protocol correctness
- Integrates with the existing PECI core infrastructure
- Allows PECI consumers (e.g. DTT, thermal, power management) to remain
transport-agnostic
A corresponding devicetree binding enables PECI-over-eSPI by defining
a PECI child node under the eSPI controller node.

Introduce CONFIG_RISCV_S_MODE to select Supervisor-mode execution.
Add depends on !RISCV_S_MODE to RISCV_PMP since PMP CSRs are
inaccessible from S-mode.
Add an M-mode SBI shim (reset.S + sbi.S) that configures exception
delegation, PMP, and counter access before dropping to S-mode via mret.
The shim handles SBI_SET_TIMER ecalls from S-mode and forwards MTIP to
STIP so the supervisor timer driver works without a full SBI firmware.
Introduce privilege-level abstractions in isr.S (RV_CAUSE, RV_EPC,
RV_STATUS, RV_TVAL, etc.) and update all runtime code that previously
accessed M-mode-only CSRs (mcause, mtval, mstatus, mie, mip) to use the
S-mode equivalents when CONFIG_RISCV_S_MODE is set.
ARCH_EXCEPT in kernel context uses ebreak (cause=3, Breakpoint) instead
of a direct z_riscv_fatal_error() call. In S-mode, ecall (cause=9) is
kept in M-mode for SBI and never reaches the S-mode exception handler;
a direct call with NULL esf caused the stack unwinder to crash into an
infinite fault loop. ebreak is delegated to S-mode by our medeleg
configuration; isr.S treats ebreak with t0=RV_ECALL_RUNTIME_EXCEPT the
same way M-mode treats ecall-based ARCH_EXCEPT.
