CONFIG_FORTIFY_SOURCE=y is already set in the generic kernel
configuration, but it is not working for MIPS on kernel 5.4, support for
MIPS was only added with kernel 5.5, other architectures like aarch64
support FORTIFY_SOURCE already since some time.
This patch adds support for FORTIFY_SOURCE to MIPS with kernel 5.4,
kernel 5.10 already supports this and needs no changes.
This backports one patch from kernel 5.5 and one fix from 5.8 to make
fortify source also work on our kernel 5.4.
The changes are not compatible with the
306-mips_mem_functions_performance.patch patch which was also removed
with kernel 5.10, probably because of the same problems. I think it is
not needed anyway as the compiler should automatically optimize the
calls to memset(), memcpy() and memmove() even when not explicitly
telling the compiler to use the build in variant.
This increases the size of an uncompressed kernel by less than 1 KB.

(cherry picked from commit 9ffa2f8193)
AR2315 Ethernet driver pass NULL instead of a real device pointer to DMA
(un-)map calls. With kernel version 5.4 such behaviour causes a kernel
panic. Fix this issue by preserving device pointer during the probe
procedure and pass it to each skb data DMA (un-)map call.

Rework ethernet supported link modes to linkmode bitmask.
This is needed to suppress compilation errors:

Kernel commit e7bfb3fdbde3 ("mtd: Stop updating erase_info->state
and calling mtd_erase_callback()") removed erase_info->state
updates and calls of mtd_erase_callback().
Drop these erase callback invocations from AR2315 MTD driver as well.

Discussion on the mailing list reveals that this target has active
users. As we are finally able to upgrade this target to kernel 5.4,
add it back to master.
This reverts commit 7d29a55714 ("ath25: drop target") and
immediately moves the relevant files to 5.4, without touching
the content.
