Wilfred Mallawa dda94e5c66 hw: timer: ibex_timer: update/add reg address
The following changes:
1. Fixes the incorrectly set CTRL register address. As
per [1] https://docs.opentitan.org/hw/ip/rv_timer/doc/#register-table

The CTRL register is @ 0x04.

This was found when attempting to fixup a bug where a timer_interrupt
was not serviced on TockOS-OpenTitan.

2. Adds ALERT_TEST register as documented on [1], adding repective
   switch cases to error handle and later implement functionality.
