Subject: [PATCH] drm/panel-edp: Add ID for KD KD116N09-30NH-A016

As evidenced by in-field reports, this panel shipped on pompom but we
never added the ID and thus we're stuck w/ conservative timings. The
panel was part of early patches but somehow got left off in the
end. :( Add it in now.

For future reference, EDID from this panel is:
00ffffffffffff002c82121200000000
321e0104951a0e780ae511965e55932c
19505400000001010101010101010101
010101010101a41f5686500084302820
55000090100000180000000000000000
00000000000000000000000000000000
000000000000000000000000000000fe
004b443131364e3039333041313600f6

We use the ASCII string from decoding the EDID ("KD116N0930A16") as
the panel name.
