[PATCH 08/62] ARM: davinci: use explicit 'select' for DA850_EVM

[Arnd Bergmann]

The DAVINCI_DA850_EVM board uses an unusual method to
enable the GPIO_PCA953X and KEYBOARD_GPIO_POLLED symbols,
which leads to the dependencies on these symbols being
ignored. As GPIO_PCA953X actually requires I2C, that
can lead to build failures when I2C is disabled.

This patch removes the duplicate symbol definitions
and instead adds equivalent 'select' statements that
are conditional on the underlying dependencies.

A different question whether we actually want to automatically
enable them at all or rather put them into defconfig,
but that should be a separate patch.
