[Buildroot] [PATCH v3 1/2] configs/qemu_sh4*: switch to initramfs

[Waldemar Brodkorb]

Qemu 9.0.0/9.0.1 has introduced a Bug in sh4/sh4eb emulation so
that the system doesn't boot anymore.
The issue is already reported by Guenter Roeck:
https://lists.nongnu.org/archive/html/qemu-devel/2024-05/msg00606.html

Switch to initramfs for sh4/sh4eb emulation.

Signed-off-by: Waldemar Brodkorb <wbx@openadk.org>
---
v2->v3:
 - separate sh4 switch to initramfs from kernel update
