[PATCH v2 3/3] hwrng: imx-rngc - use BIT(x) for register bit defines

From: Martin Kaiser
Date: Fri May 19 2023 - 12:05:44 EST


Rewrite the defines for register bits to use BIT(x) instead of writing
out the 32-bit number. This makes it easier to compare the code with the
register descriptions in the reference manual.
