David has applied this patch which is in general just the same as this one.

(linux-next) Remove architecture dependency
28811a8c00fe0d899b8a544421f3b4947425d5e8

Mark Brown has suggested to do so for spi and don't check architecture at
all.
I have also sent similar patch for watchdog driver too.

I think it is up to you if you want to add ARM64 to Kconfig or just remove
that arch dependencies.
To be honest my goal is to enable this driver for ARM64.
Please tell me what way you prefer.

Thanks,
Michal
