configs/roseapplypi_defconfig: bump kernel to 5.15.10

The kernel now has support for dma, ethernet, i2c, mmc, pinctrl, regulator,
so enable drivers for those, change to a ext4 rootfs and enable DHCP on
eth0.

Applied to master, thanks.

Will we at some point be able to drop our custom kernel config file, and
use an upstream defconfig instead?

Regards,
Yann E. MORIN.

Possibly yes. Basic owl support was added to multi_v7_defconfig with:

commit 26ba4a474aec5998e52826319c4d7a1c98e8fab5
Author: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>

    ARM: multi_v7_defconfig: Enable Actions Semi platform and drivers

    The support for Actions Semi ARM32 platform has matured enough in the
    mainline. So let's enable it in multi_v7_defconfig along with the
    relevant drivers. The platform can now boot a distro from eMMC or uSD
    without any out of tree patch.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=26ba4a474aec5998e52826319c4d7a1c98e8fab5

I haven't given it a try yet though. I'll try to find some time to do
it.
