Heinrich Schuchardt f5abd8a616 ram: k3-j721e: rename BIT_MASK() 
The macro BIT_MASK is already defined in include/linux/bitops.h. To avoid
name collisions rename BIT_MASK() in drivers/ram/k3-j721e/lpddr4_private.h
to LPDDR4_BIT_MASK().

Remove superfluous parantheses.
Remove superfluous comparison to 0.
