kernel: bump 5.10 to 5.10.76

Deleted (upstreamed):
bcm27xx/patches-5.10/950-0145-xhci-add-quirk-for-host-controllers-that-don-t-updat.patch [1]

Manually rebased:
bcm27xx/patches-5.10/950-0355-xhci-quirks-add-link-TRB-quirk-for-VL805.patch
bcm53xx/patches-5.10/180-usb-xhci-add-support-for-performing-fake-doorbell.patch

Note: although automatically rebaseable, the last patch has been edited to avoid
conflicting bit definitions.

-Subject: [PATCH] xhci: add quirk for host controllers that don't
- update endpoint DCS
-
-Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
-at least, if the xHC halts on a particular TRB due to an error then
-the DCS field in the Out Endpoint Context maintained by the hardware
-is not updated with the current cycle state.
-
-Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
-from the TRB that the xHC stopped on.
-
-See: https://github.com/raspberrypi/linux/issues/3060
