Subject: [PATCH v2 3/5] ARM: dts: qcom: msm8960: disable gsbi1 and gsbi5
 nodes in msm8960 dtsi

Not all devices use gsbi1 and gsbi5, so these nodes should be disabled
in the SoC dtsi, following the existing pattern used for gsbi3. The
upstream samsung-expressatt and msm8960-cdp devices already have status
"okay" for these nodes, so this change should not break existing
functionality.

This eliminates the following error messages when gsbi nodes are not
configured in the board's device tree:
[    1.109723] gsbi 16000000.gsbi: missing mode configuration
[    1.109797] gsbi 16000000.gsbi: probe with driver gsbi failed with error -22

(Note: Xperia SP doesn't use gsbi5)
