commit d96ac5bdc52b271b4f8ac0670a203913666b8758 upstream.
R-Car V4H Reference Manual R19UH0186EJ0130 Rev.1.30 Apr. 21, 2025 page 4581 Figure 104.3b Initial Setting of PCIEC(example), middle of the figure indicates that fourth write into register 0x148 [2:0] is 0x3 or GENMASK(1, 0). The current code writes GENMASK(11, 0) which is a typo. Fix the typo.
