x86/build: Disable HIGHMEM64G selection for M486SX
Fix a regression caused by making the 486SX separately selectable in Kconfig, for which the HIGHMEM64G setting has not been updated and therefore has become exposed as a user-selectable option for the M486SX configuration setting unlike with original M486 and all the other settings that choose non-PAE-enabled processors:
High Memory Support
- off (NOHIGHMEM)
2. 4GB (HIGHMEM4G) 3. 64GB (HIGHMEM64G) choice[1-3?]:
With the fix in place the setting is now correctly removed:
High Memory Support
- off (NOHIGHMEM)
2. 4GB (HIGHMEM4G) choice[1-2?]:
