drivers: mcux_gpt_timer: Added GPT timer for HW clock Added a driver to enable the GPT timer on RT1xxx parts to be used instead of systick as a clock source. The timer is set to run in reset mode, and uses the low frequency 32kHz oscillator for power savings Signed-off-by: Daniel DeGrasse <daniel.degrasse@nxp.com>

soc: arm: nxp: switch imxrt boards to use systick timer unless CONFIG_PM=y Switch all imxrt boards to use the systick timer by default, and only enable the GPT timer when using low power modes. This is desirable because the systick has a higher resolution, but the GPT can run while the core clock is gated, making it useful for low power modes.

help
This module implements a kernel device driver for the NXP GPT timer,
and provides the standard "system clock driver" interfaces. It uses the
first GPT peripheral defined in the system, which can no longer be used
for the GPT counter driver.
