From: Andrei Cherechesu <andrei.cherechesu@nxp.com>

Add code for NXP S32CC platforms (S32G2, S32G3, S32R45).

S32CC platforms use the NXP LINFlexD UART driver for
console by default, and rely on Dom0 having access to
SCMI services for system-level resources from firmware
at EL3.

Platform-related quirks will be addressed in following
commits.
