ARM: dts: msm: Remove duplicate I2C controller on 8994

Commit c6e4e229 ('ARM: dts:
msm: Enable BLSP11 for I2C usage') added a duplicate I2C
controller. Specifically, the newly-added i2c_11 device has
the same hardware resources as the already existing i2c_5
device. Remove the duplicate device to avoid confusion.

This reverts commit c6e4e229.
