MLK-16918-15 drm/bridge: Update adv7511 driver with some regs for adv7535

commit 0e1a0ab5fd5b17b22f2be4f4a2eefe19b09bbaf2 from
https://github.com/nxp-imx/linux-imx



The low refresh rate register for ADV7535 is in 0x4A instead of 0xFB. In
order to correctly handle these differences, add the new type ADV7535.
