The MC subsystem in Tegra210 uses a longer bitmask for the
MC_ERR_STATUS.CLIENT bitfield. Define that in the SoC-specific data
for Tegra210 so the MC code can use it.
Note that this patch does not apply to mainline in its current form.
This patch is against linux-next 20150602, plus the "memory: tegra: mc:
add support for a variable-size client ID bitfield" patch that I just sent
to the linux-tegra mailing lists, plus Thierry's Tegra210 MC patches.
Thierry's patches can currently be found in commit
c8bb81c3b132c9b3c1859cde3d7005ad8ab13862 ("CHROMIUM: memory: tegra: Add
Tegra210 support") of the chromeos-3.18 branch of
https://chromium.googlesource.com/chromiumos/third_party/kernel (but which
is undoubtedly headed upstream).
This patch is based on work by David Ung <[email protected]>.

Have done a quick build test on this internally, but not much else. I
expect Thierry to add this to his T210 MC set before posting it for
upstream consumption.
