Subject: [PATCH 2/4] gpu: host1x: Fix mask for syncpoint increment register

From: Mikko Perttunen <mperttunen@...dia.com>

On Tegra186+, the syncpoint ID has 10 bits of space. To allow
using more than 256 syncpoints, fix the mask.

Fixes: 9abdd497cd0a ("gpu: host1x: Tegra234 device data and headers")
