perf:check_valid_chip - Update test to avoid fail

Command: perf stat -v -e hv_24x7/PM_PHB0_0_CYC,domain=1,chip=<value>

Maximum chip value which can be assigned is 65535
Anything above that range should fail and this test is used
to verify that

Hence, setting invalid_chip=65536 can directly test the command
In scenarious where multiple chip values are tested, this testcase
can fail if the chip values passed before 65536 are in the accepted
range.
