gemini: Bump to kernel v5.10
Only two patches against mainline remains. Switch to v5.10 which works very nicely with all Gemini devices. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> [backported don't disable option CONFIG_BPF_SYSCAL] Signed-off-by: Christian Lamparter <chunkeey@gmail.com>

+Subject: [PATCH 1/2] usb: host: fotg2: add Gemini-specific handling
+
+The Cortina Systems Gemini has bolted on a PHY inside the
+silicon that can be handled by six bits in a MISC register in
+the system controller.
+
+If we are running on Gemini, look up a syscon regmap through
+a phandle and enable VBUS and optionally the Mini-B connector.
+
+If the device is flagged as "wakeup-source" using the standard
+DT bindings, we also enable this in the global controller for
+respective port.

+Rename the firmware partition so that the firmware MTD
