The GPC_CPU_PGC_SW_PDN_REQ offset should be 0xfc, previous
offset is incorrect, so actually ARM core is NOT powered
down and the power leakage is very high.
With this fix, each ARM core's leakage is about 25mA@0.9V.

The bits[3:0] of CPU_PGC_PUP/PDN_TRG use core's SW
power up/down. prevous bits assignment is wrong, so
fix it.

- USB PHY reset bit in SRC needs to be clear before
doing USB PHY power gating in GPC, only needs to
do once;
- Need to handle GPC_PU_PWRHSK during power up/down;
- Enable GPC pu power gate support.

As there are too many difference between each PU's power
on/off flow, here enable all PUs power until all modules'
power on/off function ready and tested, then we will enable
this PU PGC feature.

the PCIE1 and PCIE2 share the same reset signal, if PCIE2 is power down,
PCIE1 will also be power down, so when we need to power up PCIE1, the PCIE2
need to power up too, only PCIE1 is power down, the PCIE2 power domain can
be power down too

No need to enable all PU power during boot up, module driver
will enable their power domain as needed.

The power domain id does NOT equal to the register bit
offset, so need to do a mapping here.

Add hardware power down for all power domains. Make
imx_gpc_set_m_core_pgc usable for all MIX and PU PGC.

Need to mask all M4 IRQ and override all PLLs/OSC
before entering DSM mode, but due to DRAM self-refresh
NOT ready, non-fast wakeup mode is NOT working, so
we still use fast wakeup mode, which means DSM mode
by default is NOT entered.
After DRAM self-refresh is added, we will switch
to non-fast wakeup mode to make DSM work.

Add basic support for i.MX8MQ.
1. SMP support is ok.
2. basic suspend/resume support is ok.
