[PATCH AUTOSEL 5.9 25/35] drm/amd/display: adding ddc_gpio_vga_reg_list to ddc reg def'ns

[Sasha Levin]

From: Martin Leung <martin.leung at amd.com>

[ Upstream commit a1d2afc5dde29a943d32bf92eb0408c9f19541fc ]

why:
oem-related ddc read/write fails without these regs

how:
copy from hw_factory_dcn20.c
