Add WLAN card support
This is loosely based on the contents of the tar file provided with the WLAN cards (AGL_Refhw_sample_software_KK_20210225.tar.gz) with updates for BSP v4.7.0 and other fixes. Changes: - Kernel patches and configuration update to enable the TI WL1837 module. As opposed to the original changes from Panasonic or the Kingfisher support, the HCI LL driver is used instead of the older ti-st + btwilink combination, since the the latter are deprecated and are removed in kernel 5.5. - As part of the above the sound configuration in the devicetree has been reworked to support the WL1837 BT audio. This includes dropping the HDMI1 audio configuration from the original Salvator-X devicetree, as it conflicts with the SSI used for the ak4613 in the reference hardware. - Recipes added for wlconf (from meta-ti) and ti-bt-firmware (loosely derived from the meta-rcar-gen3-adas version). The TI-TFL license used by ti-bt-firmware has been added in a top-level "licenses" directory and that added to LICENSE_PATH in layer.conf to satisfy the license packaging QA checking.

+Add support for TI WL1837
+
+This patch adds description of TI WL1837 and links interfaces
+to communicate with the IC.
+
+Signed-off-by: ito.yoshiki001 <ito.yoshiki001@jp.panasonic.com>
+
+Reworked:
+- WL1837 specific devicetree configuration moved to the board
+ specific r8a7795-agl-refhw.dts from agl-refhw-common.dtsi.
+- Switched to HCI_LL driver for BT support to match other upstream
+ users and prepare for btwilink driver going away (dropped in 5.5
+ upstream).
+- WLAN_PWR_EN enabling moved to GPIO initialization to work around
+ BT initialization problems.
+- Update sound configuration to enable WL1837 BT audio, and disable
+ the HDMI1 audio left over from the original Salvator-X devicetree.
+ The latter is clean up, as HDMI1 as defined uses a SSI that
+ conflicts with the ak4613 configuration.

+Revert "wl18xx: do not invert IRQ on WLxxxx side"
+
+This reverts commit 2bcfc394307ae164cbbdff74b902af61dc0181b4.
+The hard-coded assumption that the IRQ inversion logic is not
