media: ipu6: Fix typo and wrong constant in ipu6-mmu.c

Browse Source 
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: 9163d83573 ("media: intel/ipu6: add IPU6 DMA mapping API and MMU table")
