I don't think we need multiple levels here, it should be enough to
have either ARCH_SPRD or ARCH_SHARKL64, because all device drivers
are going to be optional anyway. Typically a Kconfig symbol covers
all SoCs that are related, so if you Spreadtrum are doing both
phone and server chips and these are designed independently, you
would have two symbols, but if you only expect to see phone chips
here that are all derived from the same product line, using ARCH_SPRD
to refer to all of them should be enough.
