[PATCH 11/11] mtd: nand: Move Macronix specific initialization in nand_macronix.c

[Michael Trimarchi]

Upstream commit 3b5206f4be9b65d2f0f85b3239cf117a1d0de7ce

Move Macronix specific initialization logic into nand_macronix.c. This
is part of the "separate vendor specific code from core" cleanup
process.
