asm-generic updates for 6.4

Browse Source 
These are various cleanups, fixing a number of uapi header files to no
 longer reference CONFIG_* symbols, and one patch that introduces the
 new CONFIG_HAS_IOPORT symbol for architectures that provide working
 inb()/outb() macros, as a preparation for adding driver dependencies
 on those in the following release.
