Subject: [PATCH v5 04/10] drm/bridge: it6505: Change definition MAX_HDCP_DOWN_STREAM_COUNT

From: Hermes Wu <Hermes.wu@....com.tw>

A HDCP source device shall support max downstream to 127 devices.
Change definition MAX_HDCP_DOWN_STREAM_COUNT to 127

KSVs shall save for DRM blocked devices check.
This results in struct it6505 growth by ~0.5 KiB.
