drivers: bluetooth: hci_spi: Use DT instead of Kconfig to get HW params

Browse source 
Convert the HCI SPI driver to get the SPI and GPIO settings from Device
Tree instead of Kconfig. The "zephyr,bt-hci-spi" binding is used as
a common one for this purpose ("st,spbtle-rf" is removed), to take
advantage of the new DT_<COMPAT>_<INSTANCE> generated macros and get
rid of related fixups and aliases.
