media: ipu6: Fix typo and wrong constant in ipu6-mmu.c
Fix two coding errors in ipu6-mmu.c:
1. Fix syntax error in page_table_dump() where the closing parenthesis
and semicolon were swapped in the TBL_PHYS_ADDR macro call.
2. Fix 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.
Fixes: 9163d83573e4 ("media: intel/ipu6: add IPU6 DMA mapping API and MMU table")
