mfd: intel-m10-bmc: Fix the register access range

BugLink: https://bugs.launchpad.net/bugs/1928857
[ Upstream commit d9b326b2c3673f939941806146aee38e5c635fd0 ]

This patch fixes the max register address of MAX 10 BMC. The range
0x20000000 ~ 0x200000fc are for control registers of the QSPI flash
controller, which are not accessible to host.
