successfully build applications.
Note that SRAM1 and SRAM2 are continuous regions.

When we have skips in ctest, the overall result should not be marked as
a SKIP unless all tests have been skipped. If we have passing tests,
mark the test as PASS. Any failures/errors obviously will fail the
tests.
Also pass the skip reason from ctest to twister to give a hint about
what is going on in case of skips.

Fix timeout error that can occur in rare case.
When the thread writing to flash is pre-emptive it can be scheduled
out after reading the status register, but before checking if timeout
has expired. In this case it will report timeout without re-checking
the status register.
When writing a lot to flash, for example a firmware update process
then this situation is very likely to occur.

Several subsystems have configuration options that allow large buffers
to be placed in specialized memory sections. When PSRAM is enabled, the
MBEDTLS heap and LVGL heap and buffer can be relocated to custom sections
within the PSRAM segment.
Enabling `CONFIG_ESP_SPIRAM` together with any of the following options:
* `CONFIG_MBEDTLS_HEAP_CUSTOM_SECTION`
* `CONFIG_LV_Z_MEMORY_POOL_CUSTOM_SECTION`
* `CONFIG_LV_Z_VDB_CUSTOM_SECTION`
will place the corresponding buffers into the `.mbedtls_heap`,
`.lvgl_heap`, and `.lvgl_buf` sections, respectively.
If none of these custom section options are enabled, the buffers will
fall back to the `.ext_ram.bss` section.

When calling device_get_binding(NULL) from userspace, this eventually
funnels down to a call to arch_user_string_nlen() where it tried to
verify that the kernel has access to this address (0x0). But since
this originates from userspace, we really want to know if this is
accessible from userspace, so using arch_buffer_validate() instead
of xtensa_mem_kernel_has_access() is preferable.

This stupid errata will not leave me alone, here is another bandaid to
deal with an issue where an extra byte was being sent on version 1
LPSPIs due to the algorithm of filling NOPs when only RX is left was not
expecting the situation where the LPSPI actually consumed everything
from the fifo but is not sending it due to this ridiculous stalling errata.

The buf_len parameter of lpspi_fill_tx_fifo is supposed to be bytes, so
we do not need to convert it. This could cause an issue if the end of
the buffer is less bytes than the word size.

Fixing some issues with the TX fifo fill logic in two places:
First in the normal fill function, it didn't take into account a
situation where the TX fifo is already partially filled. This currently
doesn't cause a problem because the driver is written in a way that the
watermark is always 0 for TDF, but in case the watermark were anything
else it would cause a problem.
Second, when filling the TX fifo with NOPS in order to clock the rest of
the RX in from the bus, the calculation regarding the current TX fifo
length was just wrong and was leading to a bug in some cases where there
was a subtraction underflow and billions of NOPs were being filled.
Also, there could be a problem where a few extra NOPs are put in the TX
fifo if we don't count what we already have in the TX fifo, so fixing
that as well.

There is no need to update the tx context in interrupt instead of
directly after the fill, this just makes the code more complex. Also,
the spi context header already handled iterating over buffers so we can
remove that code too.

For optimization purpose, remove calls to SDK. Since we know exactly
what we want, this results in smaller code size.
Also, this code calculates the SCK parameters more efficiently than the
SDK driver did it by using a binary (instead of linear) search.
Lastly, remove call to LPSPI_Reset in the init call and replace with
native driver code, and remove inclusion of SDK header.
