Summary:
- I noticed that there are two kinds of descriptors for imxrt_enet.c
- The first one is the legacy descriptor and its size is 8bytes.
- The second one is the enhanced descriptor and its size is 32bytes.
- In both cases, we can not use a descriptor chain like stm32.
- Considering cache line alignment, the second one is perfect because
one descriptor fits the Cortex-M7 cache line which would fix networking
stability issues in d-cache write-back mode.
Impact:
- imxrt ethernet in d-cache write-back mode
Testing:
- Tested with ixmrt1060-evk:netnsh_dcache_wb (will be added later)

Summary:
- I noticed that CONFIG_IMXRT_ENET_ENHANCEDBD is not correctly
used though it is defined in Kconfig.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with imxrt1060-evk:netnsh_dcache_wb (will be added later)

Current implementation supports the trigger generation only from timer
capture on period value. This is sufficient for PWM synchronization but
may not be enough for other purposes as ADC triggering for example.
This change adds an option to generate the trigger based on a duty
cycle value.

Not all boards have an interrupt line from the phy to
the Soc. This commit allows the phy to be polled for
link status.
This may not work on all MAC/PHY combination that
have mutually exclusive link management and operating
modes. The STM32H7 and LAN8742AI do not have such a
limitation.
Fix typos
Config option IMXRT_ADCx_ETC can now be used to select an external HW
trigger to be used instead of continous trigger. Continous trigger is
used if IMXRT_ADCx_ETC = -1 (default option). Otherwise the source signal
is routed through XBAR and used as a trigger.
Hardware triggering is currently limited to maximum of 8 channels.
HW trigger is automatically disabled if there are more than 8 channels.
The external triggering was tested with PWM signal as a source.

This commit supplements commit 7d877fbb. External sync mode is now
disabled if XBAR connection fails and config options are used directly
in sync_src variable and passed to XBAR macro only when needed. The first
option could caused an undefined behaviour when sync_src was equal to -1
(external sync not used)

This commit allows the PWM modules to be synchronized by an external
signal (other PWM module for example). The sync source can be selected
from configuration.
PWM module can also now generate a trigger when its timer reaches the duty
cycle. This trigger is used for the synchronization of other modules. It
can also be used for triggering ADC for example in the future.
Thanks to Rastislav Pavlanin and Jan Spurek from NXP support for
suggestion which helped to solve the inter-module PWM synchronization
task.

This commit enhances imxrt encoder driver with index capture support.
The index is captured when the index interrupt occurs and can be passed
to application layer with QEIOC_GETINDEX ioctl call.
