board: ti: dra7xx: Select MCAN instead of DCAN on DRA76 EVM
MCAN can be accessed via DCAN1 or DCAN2. Determining which DCAN instance
to use if any at all is done through
CTRL_CORE_CONTROL_SPARE_RW.SEL_ALT_MCAN. Since general pinmuxing is
handled in U-boot. Handle this additional pinmuxing requirement in U-boot
to ensure that MCAN is used by default via the DCAN1 pins.
