John Audia 5e43dd1fa7 kernel: bump 5.10 to 5.10.99
Had to update generic defconfig (make kernel_menuconfig CONFIG_TARGET=generic)
for this bump, but since that only modifies the target defined in .config,
and since that target also needed to be updated for unrelated reasons, manually
propagated the newly added symbol to the generic config.

Removed upstreamed:
    pending-5.10/860-Revert-ASoC-mediatek-Check-for-error-clk-pointer.patch[1]

All other patches automatically rebased.

Subject: [PATCH] pinctrl: bcm2835: Accept fewer than expected IRQs
The downstream .dts files only request two GPIO IRQs. Truncate the
array of parent IRQs when irq_of_parse_and_map returns 0.
