turnip: Remove redundant bits override from lower_tex_ycbcr
What does this MR do and why?
This isn't needed anymore, because vk_format_get_component_bits now accesses the proper pipe formats and therefore returns the correct bit count since the following commit:
57c81bab ("vulkan/format: Translate two 420_UNORM formats properly")
I've verified that vk_format_get_component_bits
correctly returns 8 by default now for all 4 formats in the switch statement, but as far as I understand this path is only ever hit with VK_FORMAT_G8_B8R8_2PLANE_420_UNORM
and VK_FORMAT_G8_B8_R8_3PLANE_420_UNORM
currently.
