drivers: bluetooth: hci: refactor silabs controller init

Browse source 
Refactor the controller init to use the new init routines the
controller now provides. Instead of using a hardcoded set of
features, the features are now initialized based on Kconfig
values that the application selects.

Add config files under modules/hal_silabs, used by the controller
init routines in the external module hal_silabs to determine which
features to enable based on Kconfig options. This brings the
controller feature configurability to roughly parity with the
Simplicity SDK.

this hint to optimize the scheduling of concurrent connections.
This value does not preclude using longer data lengths.
config BT_SILABS_EFR32_PAWR_PACKET_REQUEST_COUNT
int "Number of PAwR packets from host per request"
default 4
range 1 12
help
The number of packets the controller requests from the host in one LE
Periodic Advertising Subevent Data Request event. This is a tradeoff
between the controller's memory usage and the number of separate HCI
events the controller must send. This value is applied to each PAwR
advertiser separately. Note that the request count is limited by the
number of subevents in the PAwR train, and the request advance
configuration.
config BT_SILABS_EFR32_PAWR_PACKET_REQUEST_ADVANCE
int "Number of subevents in advance to request PAwR data"
default 1
range 1 6
help
The controller asks the host to provide data for upcoming subevents
before the subevents are sent over the air. This parameter is used to
configure how many subevents in advance the requests are sent to the
host. The bigger the advance is, the more time the host has to
process the request, but the controller has to reserve more memory
for buffering the subevent data. Note that the maximum advance is
limited by the number of subevents configured for a PAwR train.
Therefore, the actual advance may be less than the number configured
in this parameter.
