perf arm-spe: augment the data source type with neoverse_spe list
When synthesizing event with SPE data source, commit 4e6430cbb1a9("perf
arm-spe: Use SPE data source for neoverse cores") augment the type with
source information by MIDR. However, is_midr_in_range only compares the
first entry in neoverse_spe.
Change is_midr_in_range to is_midr_in_range_list to traverse the
neoverse_spe array so that all neoverse cores synthesize event with data
source packet.
Fixes: 4e6430cbb1a9f1dc ("perf arm-spe: Use SPE data source for neoverse cores")
