Cert-C is flagging following issue in mc-err code:
cert_exp33_c_violation: Using uninitialized value status_reg when
calling mc_ch_readl.
Fix the above issue by adding a default case for MC interrupt mask and
return from there by printing the error.

Add support for mc-err driver on T264. Maintain driver similar to
current upstream mc-err driver, so that upstreaming diff for T264 would
be straight forward. Current IRQ handling logic is as follows:
- Read MCF int status from MCB
- Find out the MC channel responsible for generating error
- Read address register from that MC channel block to get the address
- Find out type of error from status register
Current implementation is as per the information received so far,
further updates will be made once HW team provide programming
guidelines.

mc-t26x driver was not getting built because it's entry was missing in
kernel-src-files-copy-list.txt. Add files required for mc-t26x in
kernel-src-files-copy-list.txt.
Also, move the mc-t26x driver to a private-soc directory to build
separately from existing files in memory/tegra directory.

Remove some of the files which were added as optional for
non-existing of T264 patches. As T264 OOT drivers are
collapsing into the core tree, remove such optional files.
