16k: core: Remove page size limitation for setting TARGET_NO_BIONIC_PAGE_SIZE_MACRO

TARGET_NO_BIONIC_PAGE_SIZE_MACRO could be enabled regardless of the
value specified by TARGET_MAX_PAGE_SIZE_SUPPORTED and hence, the check
is no longer required.

Test: lunch <target> && get_build_var TARGET_NO_BIONIC_PAGE_SIZE_MACRO
