[PATCH 15/16] arch: x86: xen: Add prototypes for functions defined in mmu.c

[Darshana Padmadas]

mmu.c defines the following functions:
__visible pteval_t xen_pte_val(pte_t pte)
__visible pgdval_t xen_pgd_val(pgd_t pgd)
__visible pte_t xen_make_pte(pteval_t pte)
__visible pgd_t xen_make_pgd(pgdval_t pgd)
__visible pmdval_t xen_pmd_val(pmd_t pmd)
__visible pmd_t xen_make_pmd(pmdval_t pmd)
__visible pudval_t xen_pud_val(pud_t pud)
__visible pud_t xen_make_pud(pudval_t pud)

Include prototypes for these files in mmu.h since no
header file declares them.

This eliminates the following warnings:
arch/x86/xen/mmu.c:410:20: warning: no previous prototype for âxen_pte_valâ [-Wmissing-prototypes]
arch/x86/xen/mmu.c:418:20: warning: no previous prototype for âxen_pgd_valâ [-Wmissing-prototypes]

arch/x86/xen/mmu.c:498:17: warning: no previous prototype for âxen_make_pmdâ [-Wmissing-prototypes]
arch/x86/xen/mmu.c:506:20: warning: no previous prototype for âxen_pud_valâ [-Wmissing-prototypes]
arch/x86/xen/mmu.c:512:17: warning: no previous prototype for âxen_make_pudâ [-Wmissing-prototypes]
