[PATCH 08/18] rtc: meson: drop needless struct meson_rtc::rtc member

[André Draszik <andre.draszik@xxxxxxxxxx>]

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.
