i3c: renesas: Reconfigure the DATBAS register on re-attach

Browse source

During re-attach, the device may change its position in the i3c->addrs[]
array. As a result, it may use a different Device Address Table Basic
Register (DATBAS), which needs to be reconfigured.

Reconfigure the DATBAS register on re-attach. Along with it update
software caches.
