configs/qemu_ppc_g3beige: update to Linux 5.15

The BLK_DEV_IDE_PMAC driver has been removed from the kernel, so use the
libata replacement PATA_MACIO. This requires enabling ATA and BLK_DEV_SD
for the disk to show up, and changing the command line to use /dev/sda.

YENTA depends on PCCARD, so enable it.

The UART does not show up in /dev without DEVTMPFS.
