wifi: rtlwifi: Constify struct rtl_hal_ops and rtl_hal_cfg

'struct rtl_hal_ops' and 'struct rtl_hal_cfg' are not modified in these
drivers.

Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

Constification of rtl_hal_cfg is only needed in rtl8192cu/sw.c

On a x86_64, with allmodconfig, as an example:
Before:
