media: staging/ipu7: Fix the loop bound in l2 table alloc

Browse Source 
This patch fixes the incorrect loop bound in alloc_l2_pt(). When
initializing L2 page table entries, the loop was incorrectly using
ISP_L1PT_PTES instead of ISP_L2PT_PTES though the ISP_L1PT_PTES is
equal to ISP_L2PT_PTES.

Fixes: 71d81c2568 ("media: staging/ipu7: add IPU7 DMA APIs and MMU mapping")
