[Discussion] variant names of MSK* are misleading

[eZioPan]

stm32-rs/peripherals/rtc/rtc_common.yaml

Lines 158 to 160 in 371fc81

	"MSK*":
	Mask: [0, "Alarm set if the date/day match"]
	NotMask: [1, "Date/day don’t care in Alarm comparison"]

In my opinion, value 0 should have NotMasked variant, and value 1 should have Masked, which is also aligned with NVIC concept: set unmask then some function activate, set mask then some function deactivate.

Or even better, I suggest to use

 "MSK1": Alarm seconds mask
   ToMatch: [0, "Alarm set if the date/day match"] 
   NotCare: [1, "Seconds don’t care in Alarm comparison"] 

to make this values more clearly.

But this modification will break current api, so maybe we need more discussion on it?

and also, MSK1 ~ MSK4 share the same description, which is not correct, and need to be too.
