Bluetooth: Populate hci_set_hw_info for Intel and Realtek
The hardware information surfaced via debugfs might be usable by the
userspace to set some configuration knobs. This patch sets the hw_info
for Intel and Realtek chipsets.
Below are some possible output of the hardware_info debugfs file.
INTEL platform=55 variant=24
RTL lmp_subver=34898 hci_rev=10 hci_ver=11 hci_bus=1
