[PATCH v2] mvebu: switch default kernel to 5.15

[Stijn Segers]

In light of https://github.com/openwrt/openwrt/issues/11077, switch mvebu
to 5.15 which has been the testing kernel on this target since April - over
half a year.

Run-tested on the following subtargets:
* cortexa9 (Turris Omnia - 03f41b1eb2f15ab06d5800274be6a67c64e2a629)
* cortexa72 (MikroTik RB5009UG+S+IN)
