[PATCH v4 5/5] da850-evm: KEYBOARD_GPIO and INPUT_POLLDEV Kconfig conditionals

[Ben Gardiner <bengardiner@nanometrics.ca>]

Use the mach-davinci/Kconfig to enable gpio-keys as default when da850-evm
machine is enabled and to also select INPUT_POLLDEV when gpio-keys is enabled.

INPUT_POLLDEV needs to be enabled for gpio-keys devices to function properly
on da850-evm.
