Add support for the OTP memory device found on the Rockchip RK3588 SoC.
While here, remove the unnecessary 'void *' casts in the OF device ID
table.

Enhance error handling in the probe function by making use of
dev_err_probe(), which ensures the error code is always printed, in
addition to the specified error message.

In preparation to support new Rockchip OTP memory devices having
specific reset configurations, switch devm_reset_control_get() to
devm_reset_control_array_get_exclusive().

In preparation to support additional Rockchip OTP memory devices with
different register layout, generalize rockchip_otp_wait_status() to
accept a new parameter for specifying the offset of the status register.

In preparation to support new Rockchip OTP memory devices with different
clock configurations and register layout, extend rockchip_data struct
with the related members: clks, num_clks, reg_read.
Additionally, to avoid managing redundant driver data, drop num_clks
member from rockchip_otp struct and update all references to point to
the equivalent member in rockchip_data.

Newer Rockchip socs like the px30 use a different one-time-programmable
memory controller for things like cpu-id and leakage information,
so add the necessary driver for it.
