In a subsequent patch, the registration callback will need more parameters
from cpg_mssr_priv (like another base address with clock controllers
with double register block, and also, notifiers and rmw_lock).
Instead of adding more parameters, move the needed parameters to a public
sub-struct.
Instead moving clks to this structure, which would have implied to add
an allocation (and cleanup) for it, keep the way the allocation is done
and just have a copy of the pointer in the public structure.

On arm32, there is no reason to use the (soon deprecated) clk_readl().
Hence use the generic readl() instead.

The OSTM timer driver for RZ/A2 uses TIMER_OF_DECLARE which requires the
ostm module clocks to be registers early in boot.

Add support for the R7S9210 (RZ/A2) Clock Pulse Generator and Module
Standby.
The Module Standby HW in the RZ/A series is very close to R-Car HW, except
for how the registers are laid out.
The MSTP registers are only 8-bits wide, there are no status registers
(MSTPSR), and the register offsets are a little different. Since the RZ/A
hardware manuals refer to these registers as the Standby Control Registers,
we'll use that name to distinguish the RZ/A type from the R-Car type.
