feat(imx8ulp): add i.MX8ULP basic support
Add the basic support for i.MX8ULP.
The i.MX 8ULP family of processors features NXP’s advanced
implementation of the dual Arm Cortex-A35 cores alongside
an Arm Cortex-M33. This combined architecture enables the
device to run a rich operating system (such as Linux) on
the Cortex-A35 core and an RTOS (such as FreeRTOS) on the
Cortex-M33 core. It also includes a Cadence Tensilica Fusion
DSP for low-power audio and a HiFi4 DSP for advanced audio
and machine learning applications.
