Subject: [PATCH] media: mtk-vcodec: fix argument used when DEBUG is defined

From: Tom Rix <trix@...hat.com>

When DEBUG is defined this error occurs

drivers/media/platform/mtk-vcodec/mtk_vcodec_enc_drv.c:306:41:
  error: ‘i’ undeclared (first use in this function)
  mtk_v4l2_debug(2, "reg[%d] base=0x%p", i, dev->reg_base[VENC_SYS]);

Reviewing the old line

	mtk_v4l2_debug(2, "reg[%d] base=0x%p", i, dev->reg_base[i]);

All the i's need to be changed to VENC_SYS.
Fix a similar error for VENC_LT_SYS.

Fixes: 0dc4b3286125 ("media: mtk-vcodec: venc: support SCP firmware")
