xtensa: hw_breakpoint: include header for missing prototype
Add the prototype for restore_dbreak() to <asm/hw_breakpoint.h> and use
that header in hw_breakpoint.c to prevent a build warning:
arch/xtensa/kernel/hw_breakpoint.c:263:6: warning: no previous prototype for 'restore_dbreak' [-Wmissing-prototypes]
263 | void restore_dbreak(void)
