soc/intel/quark: Fix legacy GPIO reads
Add missing break to LEG_GPIO_REGS case to return the correct value for
legacy GPIO reads. Fixes coverity issue CID 1357460.
Found by Coverity, Fixes:
* CID 1357460 (#1 of 1): Unused value (UNUSED_VALUE)
returned_value: Assigning value from reg_legacy_gpio_read(step->reg)
to value here, but that stored value is overwritten before it can be
used.
value_overwrite: Overwriting previous write to value with value from
reg_pcie_afe_read(step->reg).
TEST=Build and run on Galileo Gen2.
