We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.
The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.
Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.

Since some ATF versions could have cpu-idle with cpu/cluster
power off support enabled, but due to some drivers are NOT
ready to support cpu/cluster power off when idle, so i.MX8QM's
cpu-idle with cpu/cluster power off is NOT ready at all, disable
it to avoid confusion, and ATF can have the full cpu-idle support
there.

Correct pci and reserved memory for jailhouse
For i.MX8MQ, the top address are reserved for optee.
For i.MX8QXP/QM, the pci reg needs to be updated because to support
OP-TEE the memory region are moved 32MB lower.

This patch adds cpu-idle support for i.MX8QXP, since different
platforms have different cpu-idle latency value, so move the
cpu-idle node to platform dtsi.
Add GPT as platform broadcast timer, its clock and power are
managed in TF-A.

The two dts are for Jailhouse root cell and non-root linux cell.
root cell use SDHC1/UART0, non root cell use SDHC0/UART2.
UART2 is on base board with RS232 connected.
