rtc: pcf2123: Add SPI ID table

[ Upstream commit 5f84478e14aa8b43a4ea85d2e091931741947749 ]

Currently autoloading for SPI devices does not use the DT ID table, it uses
SPI modalises. Supporting OF modalises is going to be difficult if not
impractical, an attempt was made but has been reverted, so ensure that
module autoloading works for this driver by adding an id_table listing the
SPI IDs for everything.
