ARM: davinci: dm646x-evm: Simplify error handling in 'evm_sw_setup()'
There is no need to call 'gpio_free(evm_sw_gpio[i])' for these error
handling cases, it is already done in the error handling path at label
'out_free'.
Simplify the code and axe a few LoC.
While at it, also explicitly return 0 in the normal path.
