arm64: Remove the ARCH_FORCE_MAX_ORDER config input prompt

Commit 34affcd7577a ("arm64: drop ranges in definition of
ARCH_FORCE_MAX_ORDER") dropped the ranges from the config entry and
introduced an EXPERT condition on the input prompt instead.

However, starting with defconfig (ARCH_FORCE_MAX_ORDER of 10) and
setting ARM64_64K_PAGES together with EXPERT leaves MAX_ORDER 10 which
fails to build in this configuration.

Drop the input prompt for ARCH_FORCE_MAX_ORDER completely so that it's
no longer configurable. People requiring a higher MAX_ORDER should send
a patch changing the default, together with proper justification.
