memory: gpmc: fix out of bounds read and dereference on gpmc_cs[]
Currently the array gpmc_cs is indexed by cs before it cs is range checked
and the pointer read from this out-of-index read is dereferenced. Fix this
by performing the range check on cs before the read and the following
pointer dereference.
Addresses-Coverity: ("Negative array index read")
Fixes: 9ed7a776eb50 ("ARM: OMAP2+: Fix support for multiple devices on a GPMC chip select")
