a2331c8a61 board/qemu/sh4-r2d: fix sh4 kernel bug with binutils 2.33
Remove the binutils patch reverting [1] that triggers a sh4 kernel bug
with binutils >= 2.33. Instead, add two kernel patches provided by
Alan Modra [2] that fix alignment of rodata.

2a7982ee52 configs/qemu_sh4{, eb}-r2d: remove kernel patch "restore the old sh-sci driver behaviour"
This reverts commit f7a887c368 and
23aee3eac4 since the kernel patch
is not needed as soon as qemu >= 3.1.0 is used with a kernel >=
4.11-rc1.

The qemu emulation of sh-sci driver was fixed by adding basic
timeout handling for 9600 bps [1].
