[Skiboot] [PATCH] trival: Remove an extra reg read of VUART1_GCTRLA

[Balbir singh]

The comments did not say if the read was needed to
ensure the previous write completed, but otherwise
the read is followed by a read of VUART1_GCTRLB and the
value of v is discarded.

NOTE: As you might suspect I have no way of testing this
except for compile testing it
