media: arch: sh: migor: Fix TW9910 PDN gpio
The TW9910 PDN gpio (power down) is listed as active high in the chip
manual. It turns out it is actually active low as when set to physical
level 0 it actually turns the video decoder power off.
Without this patch applied:
tw9910 0-0045: Product ID error 1f:2
With this patch applied:
tw9910 0-0045: tw9910 Product ID b:0
Fixes: commit "186c446f4b840bd77b79d3dc951ca436cb8abe79"
