platform: tegra: Add support for mask with 1s

Currently, the value of prod setting are applied if mask
bit is 0 for given value. This is non-traditional style of
defining mask.

Add support a traditional way of defining mask like if mask bits
are 1s then only apply the value of those bits.

	reg = (reg & ~mask) | (reg & mask);

This mechanism is selected via DT property to have backward
compatibility. The DT property is "mask-one-style" which can be
added under prod-setting node.
