Current mc-utils driver is specific to T234 without any support for
extending it to future SOCs. Add such support so that it can be easily
extended for future chips.
- Create a struct of function pointers of all present operations
- Set these function pointers as per SOCs

EMC registers are currently accessed to get DRAM parameters.
As these are platform specific and static, DRAM parameters are added in
device-tree. In case of hypervisor environment, read DRAM properties
from device-tree instead of accessing EMC registers.
Also, MC and EMC register access by kernel is going to be blocked from
hypervisor. So, remove access to these registers.

The mc-utils driver shares a Makefile with several others drivers in the
drivers/platform/tegra directory and this means that we cannot compile
the mc-utils driver independently of these other drivers and package the
mc-utils driver without all of the other drivers. Therefore, move the
mc-utils driver into its own sub-directory and add its own Makefile so
that we can build and package this driver independently.
