[PATCH] alpha: add simd_enabled argument to perf_reg_validate()

["Thomas Weißschuh" <thomas.weissschuh@linutronix.de>]

Align the alpha function with the generic function signature.
The alpha function was added in commit 9280e99d87dd ("alpha: add
HAVE_PERF_REGS and HAVE_PERF_USER_STACK_DUMP support") while the
generic function signature was changed in commit a2c64c74c029 ("perf:
Enhance perf_reg_validate() with simd_enabled argument").

After both commits landed in Linus' tree the signatures now differ,
resulting in a build error:

arch/alpha/kernel/perf_regs.c:46:5: error: conflicting types for 'perf_reg_validate'; have 'int(u64)' {aka 'int(long long unsigned int)'}
   46 | int perf_reg_validate(u64 mask)
      |     ^~~~~~~~~~~~~~~~~
In file included from include/linux/perf_event.h:50,
                 from arch/alpha/kernel/perf_regs.c:4:
include/linux/perf_regs.h:13:5: note: previous declaration of 'perf_reg_validate' with type 'int(u64,  bool)' {aka 'int(long long unsigned int,  _Bool)'}
   13 | int perf_reg_validate(u64 mask, bool simd_enabled);
      |     ^~~~~~~~~~~~~~~~~

Add the missing argument.
