drm/bridge: it6505: Add range and selector_reg
There are 2 banks on it6505, and when writing to different bank,
REG_BANK_SEL needs to be set to the targeted bank. The current code set
this additionally, which causes a race condition when a process is
writing bank 0 registers while another process set the bank to 1. Set
ranges in regmap config so the regmap API would handle the bank changes.
