Map all clock-controller memory region in a single block.
This patch does not introduce any backward incompatibility since the dts
for EN7581 SoC is not upstream yet.

Move en7581_reset_register routine in en7581_clk_hw_init() since reset
feature is supported just by EN7581 SoC.
Get rid of reset struct in en_clk_soc_data data struct.

Introduce en7581_base_clks array in order to define per-SoC fixed-rate
clock parameters and fix wrong parameters for emi, npu and crypto EN7581

Introduce chip_scu regmap pointer since EN7581 SoC will access chip-scu
memory area via a syscon node. Remove first memory region mapping
for EN7581 SoC. This patch does not introduce any backward incompatibility
since the dts for EN7581 SoC is not upstream yet.

Move en7523_register_clocks routine in hw_init callback.
Introduce en7523_clk_hw_init callback for EN7523 SoC.
This is a preliminary patch to differentiate IO mapped region between
EN7523 and EN7581 SoCs in order to access chip-scu IO region
<0x1fa20000 0x384> on EN7581 SoC as syscon device since it contains
miscellaneous registers needed by multiple devices (clock, pinctrl ..).

REG_PCIE*_MEM and REG_PCIE*_MEM_MASK regs (PBUS_CSR memory region) are not
part of the scu block on the EN7581 SoC and they are used to select the
PCIE ports on the PBUS, so remove this configuration from the clock driver
and set these registers in the PCIE host driver instead.
This patch does not introduce any backward incompatibility since the dts
for EN7581 SoC is not upstream yet.

Introduce div_offset field in en_clk_desc struct in order to fix rate
divider estimation in en7523_get_div routine for slic and spi fixed
rate clocks.
Moreover, fix base_shift for crypto clock.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.
