[ Upstream commit 22f8d5a1bf230cf8567a4121fc3789babb46336d ] When use goldfish rtc, the "hwclock" command fails with "select() to /dev/rtc to wait for clock tick timed out". This is because "hwclock" need the set_alarm() hook to enable interrupt when alrm->enabled is true. This operation is missing in goldfish rtc (but other rtc drivers, such as cmos rtc, enable interrupt here), so add it.

[ Upstream commit 4df2ef85f0efe44505f511ca5e4455585f53a2da ]
Commit c8ff5841a90b ("rtc: pl031: switch to rtc_time64_to_tm/rtc_tm_to_time64")
seemed to have accidentally removed the call to pl031_alarm_irq_enable
from pl031_set_alarm while switching to 64-bit apis.
Let us add back the same to get the set alarm functionality back.

[ Upstream commit 3180cfabf6fbf982ca6d1a6eb56334647cc1416b ]
Unbreak CPCAP driver, which has one more bit in the day counter
increasing the max. range from 2014 to 2058. The original commit
introducing the range limit was obviously wrong, since the driver
has only been written in 2017 (3 years after 14 bits would have
run out).
