[PATCH v2 1/4] media: verisilicon: Size the VP8 segment map for the largest frame

[Arun Iyengar via B4 Relay <devnull+aiyengar1990.gmail.com@kernel.org>]

From: Arun Iyengar <aiyengar1990@gmail.com>

The segment map is sized at STREAMON, but the CAPTURE format can grow
while streaming and overrun it. Size it for the largest frame, as VP9
does.

Fixes: bbd267daf4fc ("media: verisilicon: vp9: Allow to change resolution while streaming")
