we will use timer in pmusarm, when logic power rail shutdown,
the secure timer will gone, so need to initial it in pmusram.

we do not have enough pmusram space now, so use slice1 to restore
ddr slice1 ~ slice4, that's will save more pmusram space.

when logic power rail shutdown, CRU register will back to reset
value, ddr use abpll as clock source when do suspend, we need to save
and dpll value in pmusram, then set back these ddr clock back to dpll
when dddr resume.

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions to this change in order to retain
header groupings and where there are headers within #if statements.

This moves the DRAM restore code to PMUSRAM. This is so that the
voltage domain that contains the SRAM that it was stored in before may
be turned off during system suspend.

This converts two functions to use for-loops. This saves a bit of
space to help moving DRAM resume code to PMUSRAM.

The removed if statement would make the same check that the for loop
it is in does to break out of the for loop, so it doesn't make any
sense to keep it there.

This removes the mmio_... function calls to set the multicast bit for
the PHY registers when overriding the write leveling values. These are
not needed since multicast is set by default when calling the
function, and it's also better not to leave the side effect of
disabling multicast when exiting the function.

This removes the phy_dll_bypass_set function as it is unneeded. The
values that function sets are saved during suspend, so the proper
values will be restored on resume.

This removes the space allocation for the unused PHY register space.
For instance in PHY registers 0-127, only 0-90 are used, so don't save
the 91-127 registers. This saves about 1.6KB of space.

We were getting far off values on resume for the RX_CAL_DQS values.
This saves and restores the values for suspend/resume until the root
of the problem is figured out

The goal is that make clear the secure and SoC codes. Now cleaning them
will help secure code extensions for RK3399 in the future.

This patch sets the frequency configuration of the next DRAM DFS index
to the configuration of the current index. This does not perform a
frequency transition. It just configures registers so the training on
resume for both indices will be correct.

This patch intend to support save the registers of the DDR controller
and PHY before suspend, and restore them after resume.
