Enabling the compile test should not cause automatic enabling of all
drivers. Restrict the default to ARCH also for individual driver, even
though its choice is not visible without selecting parent Kconfig
symbol, because otherwise selecting parent would select the child during
compile testing.

For the declaration of parent clocks, use struct clk_parent_data instead
of a string. Due to the change in the passed arguments, replace the usage
of devm_clk_hw_register_mux() with clk_hw_register_mux_parent_data() for
all cases.

The constant hex values used to define register offsets were written
in uppercase. This patch update all these constant hex values to
be lowercase.

Moved the declaration of extern functions ma35d1_reg_clk_pll() and
ma35d1_reg_adc_clkdiv() from the .c files to the newly created header
file clk-ma35d1.h.

The clock controller generates clocks for the whole chip, including
system clocks and all peripheral clocks. This driver support ma35d1
clock gating, divider, and individual PLL configuration.
There are 6 PLLs in ma35d1 SoC:
- CA-PLL for the two Cortex-A35 CPU clock
- SYS-PLL for system bus, which comes from the companion MCU
and cannot be programmed by clock controller.
- DDR-PLL for DDR
- EPLL for GMAC and GFX, Display, and VDEC IPs.
- VPLL for video output pixel clock
- APLL for SDHC, I2S audio, and other IPs.
CA-PLL has only one operation mode.
DDR-PLL, EPLL, VPLL, and APLL are advanced PLLs which have 3
operation modes: integer mode, fraction mode, and spread specturm mode.
