da850evm: Use clrbits function with correct endianess
The current code uses clrbits_be32 which is incorrect since we are on
a little endian machine here. This patch fixes this issue and also removes
some unnecessary code: Reading the current GPIO bank state is not required
if we are using the SET and CLEAR GPIO registers for setting/clearing
bits.
