drivers: i2c: fix a compilation dependency issue

Browse Source 
Fix a compilation warning. Compilation of the i2c driver
requires QMSI dma object file. As a solution, the current
code has "selects DMA_QMSI" in i2c Kconfig. This results
in a compilation warning since "select DMA" is also
required. Adding "select DMA" and "select DMA_QMSI"
together in i2c Kconfig can solve the compilation issue.
But, this will cause the dma driver be unnecessarily
enabled. So, the solution is to fix the issue in the QMSI
part instead of in the shim driver.
