    Fix -Wmissing-prototypes warnings:
    
      arch/x86/mm/init.c:81:6:
      warning: no previous prototype for ‘x86_has_pat_wp’ [-Wmissing-prototypes]
      bool x86_has_pat_wp(void)
    
      arch/x86/mm/init.c:86:22:
      warning: no previous prototype for ‘pgprot2cachemode’ [-Wmissing-prototypes]
      enum page_cache_mode pgprot2cachemode(pgprot_t pgprot)
    
    by including the respective header containing prototypes. Also fix:
    
      arch/x86/mm/init.c:893:13:
      warning: no previous prototype for ‘mem_encrypt_free_decrypted_mem’ [-Wmissing-prototypes]
      void __weak mem_encrypt_free_decrypted_mem(void) { }
    
    by making it static inline for the !CONFIG_AMD_MEM_ENCRYPT case. This
    warning happens when CONFIG_AMD_MEM_ENCRYPT is not enabled (defconfig
    for example):
    
      ./arch/x86/include/asm/mem_encrypt.h:80:27:
      warning: inline function ‘mem_encrypt_free_decrypted_mem’ declared weak [-Wattributes]
      static inline void __weak mem_encrypt_free_decrypted_mem(void) { }
                              ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    
    It's ok to convert to static inline because the function is used only in
    x86. Is not shared with other architectures so drop the __weak too.
    
     [ bp: Massage and adjust __weak comments while at it. ]
