No "default n" as that is the default. And we (a) need some depends on
for what families this is found on and then (b) how, if at all, does
this match up with the 32k crystal used on other TI reference platforms
over the years? If this is specific to the K3 families of reference
platforms, the help needs re-phrasing and the filename is too generic.
It's also not a "RTC" in terms of something we can talk to via
drivers/rtc/rtc-uclass.c and drivers/rtc/davinci.c, or in this case
porting the kernel's drivers/rtc/rtc-ti-k3.c over, yes?

Oh, and "U-Boot" not "Uboot". Should see if the checkpatch typo list
can be easily expanded by us, one of these days.
