[dts] [PATCH V1 1/2] tests/cvl_limit_value_test: modify maximum value of switch rule

confirm with developer that CVL support up to 32K FLU entries.Firmware allocates some
default entries first, the actual entries can't be calculated and depend on hardware.
there is no formula to figure out the specific rule numbers of different environment
configurations,so can't acquire the actual number of free entries.
dts case needs to modify the maximum value of switch rule to a proper value
