can: c_can: Add syscon/regmap RAMINIT mechanism
Some TI SoCs like DRA7 have a RAMINIT register specification
different from the other AMxx SoCs and as expected by the
existing driver.
To add more insanity, this register is shared with other
IPs like DSS, PCIe and PWM.
Provides a more generic mechanism to specify the RAMINIT
register location and START/DONE bit position and use the
syscon/regmap framework to access the register.
