That's just exactly the same thing twice for no value. Just rename it to
ACLINT_SSWI and have a list of supported chips in the help text.

The only issue with the rename is, that oldconfig will drop the then
non-existing THEAD_C900_ACLINT_SSWI entry in the previous config. That's
not the end of the world and if really desired this can be solved by
having:

config ACLINT_SSWI
	bool "RISCV ACLINT ...."
	depends on RISCV
	depends on SMP
	select IRQ_DOMAIN_HIERARCHY
	select GENERIC_IRQ_IPI_MUX
	select ACLINT_SSWI
	help
	  This enables support for ACLINT SSWI device on THEAD C9XX and
	  MIPS P8700 devices.

# Backwards compatibility so oldconfig does not drop it.
config THEAD_C900_ACLINT_SSWI
	select ACLINT_SSWI

Or something like that.
