drm/bridge: lt9211: Drop check for last nibble of version register

[ Upstream commit db74b04edce1bc86b9a5acc724c7ca06f427ab60 ]

There is now a new LT9211 rev. U5, which reports chip ID 0x18 0x01 0xe4 .
The previous LT9211 reported chip ID 0x18 0x01 0xe3 , which is what the
driver checks for right now. Since there is a possibility there will be
yet another revision of the LT9211 in the future, drop the last version
nibble check to allow all future revisions of the chip to work with this
driver.

This fix makes LT9211 rev. U5 work with this driver.
