The following patch will need to handle properties registration during
class_init time. Let's use a device_class_set_props() setter.

The current PL031 RTCICR register implementation always clears the
IRQ pending status on a register write, regardless of the value the
guest writes.
To justify that behavior, it references the ARM926EJ-S Development
Chip Reference Manual (DDI0287B) and indicates that said document
states that any write clears the internal IRQ state. It is indeed
true that in section 11.1 this document says:
"The interrupt is cleared by writing any data value to the
interrupt clear register RTCICR".
However, later in section 11.2.2 it contradicts itself by saying:
"Writing 1 to bit 0 of RTCICR clears the RTCINTR flag."
The latter statement matches the PL031 TRM (DDI0224C), which says:
"Writing 1 to bit position 0 clears the corresponding interrupt.
Writing 0 has no effect."
Let's assume that the self-contradictory DDI0287B is in error, and
follow the reference manual for the device itself, by making the
register write-one-to-clear.

[PMM: updated commit message to note that DDI0287B says two
conflicting things]

The PL031 is a Real Time Clock, not a timer.
Move it under the hw/rtc/ subdirectory.
