rtc: pl030: drop needless struct pl030_rtc::rtc member

Browse source 
The memory pointed to by the ::rtc member is managed via devres, and
no code in this driver uses it past _probe().

We can drop it from the structure and just use a local temporary
variable, reducing runtime memory consumption by a few bytes.
