mtd: msm_qpic_nand: Use logical unit count in flash density

Browse source 
In an ONFI compliant devices, the flash parameters are calculated
by reading the onfi parameter page of the device.

Existing flash density is calculated based on a single logical
unit(LUN). This shows wrong density information on Multi LUN flashes.
So, always use number of LUNS value in flash density calculations.
