Redefine mask of host-controlled feature bits to include only features
that are supported by the controller. This fixes a conformance test
failure where setting an unsupported host-controlled feature bit was
not rejected as it should.
Set the Connected Isochronous Streams (Host Support) bit from the host
only if unicast support is configured to avoid failures in
broadcast-only configurations.

The address type in the periodic adveritising sync
established event is incorrectly set to 0x01
(BT_ADDR_LE_RANDOM) when the address is a resolved one,
where it should have been BT_ADDR_LE_RANDOM_ID.
The address type has been fixed by offsetting by 2 to get
BT_ADDR_LE_PUBLIC_ID or BT_ADDR_LE_RANDOM_ID when the
address has been resolved.

The nRF HW models have been updated to correspond to a 52833 instead
of a 52832. Let's follow them.
The motivation for the change is to enable proper BIS encryption support
(for BT LE Audio ISO).
Changes:
* Point in manifest to latest HW models
* SOC_COMPATIBLE_NRF52832 has been removed, and SOC_COMPATIBLE_NRF52833
added in its place (with no uses at this point)
* Where SOC_COMPATIBLE_NRF52832 was used to set encryption like for a 52832
(to avoid using the MAXPACKETLENGHT), we set the condition to just
SOC_NRF52832.
Note: The MAXPACKETLENGHT register exists in the new simulated nrf52833,
thought it does nothing.
* In the BLE ctrl LLL radio HAL, all macros are renamed accordingly
(timings are NOT changed).
* Board dts definition now refers to the 52833 soc definition. New 52833
features set as not supported by now.
