soc/intel/braswell: fix PCI resource PMAX/PLEN values 

Without PMAX correctly set, the calculation for PLEN is incorrect,
leading to a Windows BSOD on boot.  Correct PMAX using code from
Baytrail SoC, setting PMAX to (CONFIG_MMCONF_BASE_ADDRESS - 1).

Test: Boot Windows 10 on google/edgar without BSOD.
