Lars-Peter Clausen 328f494d95 regmap: regcache-rbtree: Fix present bitmap resize
When inserting a new register into a block at the lower end the present
bitmap is currently shifted into the wrong direction. The effect of this is
that the bitmap becomes corrupted and registers which are present might be
reported as not present and vice versa.

Fix this by shifting left rather than right.
