QMAP value contains information about QSPI chip-selects.
These bits are used to display information of boot device
in checkboard() function.

QMAP value is stored in most significant 3-bits
of 8-bit register brdcfg[0] in Qixis, this patch
corrects code to get QMAP bits using below logic:
	(brdcfg[0] >> 5) & 0x7
