drivers: counter: imx_epit: Convert driver to new DT_INST macros

Browse source 
Convert driver to use DT_INST macros and remove related board per
instance Kconfig symbol usage.

Also update counter_basic_api test to use DT_INST and remove the
udoo_neo_full_m4.conf as its not longer needed since the per instance
Kconfig sybmols don't exist anymore.
