mfd: stmpe: Fix bit clearing on STMPE1600
GPIO bits clearing on pins assigned to STMPE1600 had no effects due to missing "clear registers" settings within stmpe1600_regs[]. STMPE1600 does not have dedicated "clear registers", but single "set/clear registers", hence stmpe1600_regs[] "clear registers" (STMPE_IDX_GPCR_XXX) must be set to same value as "set registers" (STMPE_IDX_GPSR_XXX), ie STMPE1600_REG_GPSR_XXX.
