misc: at25: Make driver OF independent again

[ Upstream commit 5b557298d7 ]

The commit f60e707490 ("misc: at25: Make use of device property API")
made a good job by enabling the driver for non-OF platforms, but the
recent commit 604288bc61 ("nvmem: eeprom: at25: fix type compiler warnings")
brought that back.

Restore greatness of the driver once again.

Fixes: eab61fb1cc ("nvmem: eeprom: at25: fram discovery simplification")
Fixes: fd307a4ad3 ("nvmem: prepare basics for FRAM support")
