58d3d5e79e rtc: brcmstb-waketimer: Set wktmr prescaler
The HW default is one tick per second, however instead of assuming this,
lets make sure the waketimer is actually one tick per second before
arming the alarm.

c4f07ecee2 rtc: brcmstb-waketimer: Add Broadcom STB wake-timer
This adds support for the Broadcom STB wake-timer which is a timer in
the chip's 27Mhz clock domain that offers the ability to wake the system
(wake-up source) from suspend states (S2, S3, S5). It is supported using
the rtc framework allowing us to configure alarms for system wake-up.
