board: ti: DRA7: Add DRA72-rev C evm pinmux
Add the pinmux data for rev C evm. This is different from previous revisions of the platform thanks to the deltas introduced both from silicon side and from SoC side. Based on J6EcoES2_EVM_Base_Config-20160309b and PCT-DRA72x-v1.3.0.7 for SR2.0 silicon. Signed-off-by: Nishanth Menon <nm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
