Add D_CAN raminit support to C_CAN driver to enable D_CAN RAM, which holds all the message objects during transmission or receiving of data. This initialization/de-initialization should be done in synchronous with D_CAN clock. In case of AM335X-EVM (current user of D_CAN driver) message RAM is controlled through control module register for both instances. So control module register details is required to initialization or de-initialization of message RAM according to instance number. Control module memory resource is obtained from D_CAN dt node and instance number obtained from device tree aliases node. This patch was tested on AM335x-EVM along with pinctrl data addition patch, d_can dt aliases addition and control module data addition. pinctrl data addition is not added to am335x-evm.dts (only supports CPLD profile#0) because d_can1 is supported under CPLD profile#1.
