This change is needed for adding future new SpacemiT K3 reset driver.

Since both K1 and K3 reset code register via the same module which its
name changed to spacemit_ccu, it's necessary to encode the platform/SoC
in the reset auxiliary device name to distinguish them, otherwise two
reset drivers will claim to support same "compatible" auxiliary device
even in the case of only one CCU clock driver got registered, which in
the end lead to a broken reset driver.

This change will introduce a runtime break to reset driver, and will be
fixed in follow-up commit:
ecff77f7c041 ("reset: spacemit: fix auxiliary device id")
