[PATCH 6.12.y] drm/sysfb: ofdrm: Fix is_avivo() constant comparison bug

[Sasha Levin <sashal@kernel.org>]

From: Shixiong Ou <oushixiong@kylinos.cn>

[ Upstream commit 958f35cbb8955ca3fa439cd9f2092cb42414aa8c ]

The is_avivo() function has a logic error where it compares a constant
to another constant instead of checking the device parameter:

  (PCI_VENDOR_ID_ATI_R600 >= 0x9400)
