configs/minnowboard_max_defconfig: bump kernel to 5.10.11

Explicitly enable PCI support in the kernel after commit eb01d42a77785 (PCI:
consolidate PCI config entry in drivers/pci) and change to GPT partitions /
root=PARTLABEL to find the rootfs instead of hardcoding /dev/mmcblk2p2 as
the mmc probing order has changed since commit 21b2cec61c04bd1 (mmc: Set
PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.4).

This has the additional advantage that the same image will work when written
to a USB drive instead of a microsd.
