ARM: dts: msm8660: Mark two GSBI blocks "disabled"

The GSBI module complains:

gsbi 16500000.gsbi: missing mode configuration
gsbi: probe of 16500000.gsbi failed with error -22
gsbi 16600000.gsbi: missing mode configuration
gsbi: probe of 16600000.gsbi failed with error -22
gsbi 19800000.gsbi: GSBI port protocol: 2 crci: 0

So we should mark these GSBIs as "disabled" in the SoC
file by default.

If boards appear that make use of them, we can simply
set status = "ok" in the DTS for them.
