bluetooth: Add bluetooth slimbus slave drivers

Includes BT slimbus slave driver

In Kconfig,removed BTFM_SLIM as default from BTFM_SLIM and leaf drivers.
Remove depends on to remove recursive dependencies and use select to set
the symbol to set dependency properly in defconfig by developer .

Due to component driver changes in ALSA, some of the api used in
bluetooth slave driver needs to be changed accordingly.
Changes have been made for the same.

Ported from msm-4.14 commit 4da0d05e9e61
("bluetooth: Add snapshot of bluetooth components").
