lib: utils/ipi: Fix size check in aclint_mswi_cold_init()
Currently, the ACLINT MSWI size check is forcing size to be at least 0x4000. This is inappropriate check because most systems will never utilize full 16KB for a single ACLINT MSWI device so instead we should check that ACLINT MSWI size is enough for on the associated HARTs.
