Add driver for controlling the reset lines of AN7581. This is a detached
version of the clock controller driver present in Linux only used to
control reset lines. Driver gets loaded with the bind of the clock
driver and doesn't require a compatible. This is needed as they share
the same registers.

Add support for Airoha AN7581 SoC clock driver. This mainly needed for
eMMC support to correctly get the current clock applied.
Based on the Linux clk-en7523.c but majorly reworked for U-Boot that
doesn't require CCF subsystem.
Major modification, support for set_rate, realtime get_rate and split
for reset part to a different driver.
