The i.MX 7ULP family of processors features NXP's advanced implementation
of the Arm Cortex-A7 core, the Arm Cortex-M4 core, as well as a 3D and 2D
Graphics Processing Units (GPUs).
This patch aims to add the initial support including:
1) CLK
2) GPIO PTC, PTD, PTE, PTF
3) uSDHC 1/2
4) LPUART 4/5/6/7
5) LPI2C 6/7

ChangeLog:
v2->v3:
* change to generic node names
* remove arch timer due to:
1) arch timer is fixed to 1Mhz which is lower accurate than TPM timer (3Mhz).
2) no firmware progrem CNTFREQ
3) cpuidle driver is still not in tree will may cause system hang
v1->v2:
* update clk part due to binding change
* separate soc.dtsi from board.dts
