Advantech SOM-6896 is a Broadwell U based COM Express Compact Module
Type 6. This patch adds support for it as a coreboot payload.
On board SATA and SPI are functional. On board Ethernet isn't functional
but since it's optional and ties up a PCIe x4 that is otherwise brought
out, this isn't a concern at the moment. USB doesn't work since the
xHCI driver appears to be broken.

sunxi: Remove board defconfig-s for specific Q8 tablet PCB-s
We now have generic q8_a?3_defconfig files for Q8 formfactor tablets with
an A13 / A23 / A33 SoC, there is no need for these PCB variant specific
defconfig-s and they only serve to confuse the user.
Note that in case of the forfun_q88db_defconfig and TZX-Q8-713B7_defconfig
for A13 based Q8 tablets there is not even a dts file for these in the
upstream kernel, which is all the more reason to remove them.
The generic q8_a?3_defconfig files have been tested on an Et_q8_v1_6,
Ippo_q8h_v1_2_a33_1024x600, Ippo_q8h_v1_2 and TZX-Q8-713B7 tablet, and the
forfun_q88db_defconfig is identical to q8_a13_tablet_defconfig.
This leaves only the Ippo_q8h_v5 untested with the new generic defconfigs
but there is no reason to assume that it will not work.

sunxi: Switch to using malloc_simple for the spl
common/dlmalloc.c is quite big, both in .text and .data usage. E.g. for a
Mele_M9 sun6i board build this reduces .text from 0x4214 to 0x3b94 bytes,
and .data from 0x54c to 0x144 bytes.

sunxi: Enable CONFIG_SPL_STACK_R
Select CONFIG_SPL_STACK_R for sunxi boards, this gives us much more
room on the stack once we've the DRAM running.
Besides being a good change to have on itself, this also paves the
way for switching to using malloc_simple in the SPL which cuts of
close to 4KiB of the SPL size.

malloc_simple: Add support for switching to DRAM heap
malloc_simple uses a part of the stack as heap, initially it uses
SYS_MALLOC_F_LEN bytes which typically is quite small as the initial
stacks sits in SRAM and we do not have that much SRAM to work with.
When DRAM becomes available we may switch the stack from SRAM to DRAM
to give use more room. This commit adds support for also switching to
a new bigger malloc_simple heap located in the new stack.
Note that this requires spl_init to be called before spl_relocate_stack_gd
which in practice means that spl_init must be called from board_init_f.
