hwclock: add get/set parameters option
In kernel 5.16 special ioctls were introduced to get/set RTC parameters.
Add option to get/set parameters into busybox version of hwclock.
Implementation is similar to the one already used in linux-utils hwclock
tool.
Example of parameter get use:
$ hwclock -g 2
The RTC parameter 0x2 is set to 0x2.
$ hwclock --param-get bsm
The RTC parameter 0x2 is set to 0x2.
Example of parameter set use:
$ hwclock -p 2=1
The RTC parameter 0x2 will be set to 0x1.
$ hwclock -p bsm=2
The RTC parameter 0x2 will be set to 0x2.
