This patch adds automatic configuration for the ADM CRCI muxing required to
support DMA operations for GSBI clients.  The GSBI mode and instance determine
the correct TCSR ADM CRCI MUX value that must be programmed so that the DMA
works properly.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

since commit 31964ffe ("tty: serial: msm: Remove direct access to GSBI")'
serial hangs if earlyprintk are enabled.

This hang is noticed only when the GSBI driver is probed and all the
earlyprintks before gsbi probe are seen on the console.
The reason why it hangs is because GSBI driver disables hclk in its
probe function without realizing that the serial IP might be in use by
a bootconsole. As gsbi driver disables the clock in probe the
bootconsole locks up.

Turning off hclk's could be dangerous if there are system components
like earlyprintk using the hclk.

This patch fixes the issue by delegating the clock management to
probe and remove functions in gsbi rather than disabling the clock in probe.

The GSBI (General Serial Bus Interface) driver controls the overarching
configuration of the shared serial bus infrastructure on APQ8064, IPQ8064, and
earlier QCOM processors.  The GSBI supports UART, I2C, SPI, and UIM
functionality in various combinations.
