Arnd Bergmann 1ae37d3551 nvmem: airoha: add ARM64 dependency
The driver already depends on HAVE_ARM_SMCCC and ARCH_AIROHA, but both
are available for 32-bit and 64-bit targets. However, the smccc invocation
fails on thumb2 builds with clang:

drivers/nvmem/airoha-smc-efuses.c:38:2: error: write to reserved register 'R7'
   38 |         arm_smccc_1_1_invoke(AIROHA_SMC_EFUSE_FID,
      |         ^
note: (skipping 1 expansions in backtrace; use -fmacro-backtrace-limit=0 to see all)
arch/arm/include/asm/opcodes.h:215:2: note: expanded from macro '__inst_arm_thumb32'
  215 |         __inst_thumb32(thumb_opcode)
      |         ^

Since the driver is only used on the 64-bit an7581 soc, avoid this
problem with a stricter dependency.
