Due to multiple customer requests we are deprecating the MEC5 HAL.
Customers prefer all code to be in the main Zephyr tree. They do
not want a dependency on an outside SoC HAL. These changes remove
the MEC5_HAL select from MEC165xB, MEC174x, and MEC175x. The SoC
code calling the HAL for debug configuration was replaced with
a small amount of code common to all SoC's. We also moved all
the common header includes into a common SoC header to prevent
changing multiple files if new common headers are added.
Note: the in-tree drivers: kernel timer, GPIO, PINCTRL, and UART
are all non-HAL.
