This patch adds support for programming of the StratixV FPGAs. Programming
is done in this case (board theadorable) via SPI. The board may provide
board specific code for bitstream programming.
This StratixV support will be used by the theadorable board.

Add code necessary to program the FPGA part of SoCFPGA from U-Boot
with an RBF blob. This patch also integrates the code into the
FPGA driver framework in U-Boot so it can be used via the 'fpga'
command.

V2: Move the not-CPU specific stuff into drivers/fpga/ and base
this on the cleaned up altera FPGA support.
- Descend into drivers/fpga/ only when CONFIG_FPGA=y
- Descend into drivers/bios_emulator only when CONFIG_BIOSEMU=y

Devcfg device requires to load bitstream in binary format.
But u-boot also has an option for loading bitstream in bit
format. Let's handle both cases by zynqpl driver.
Also add suport for loading partial bitstreams.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

The patch adds support to load a Lattice's bitstream
image (called VME file) into a Lattice FPGA. The code
containing the state machine delivered as part of
Lattice's ispVMtools is integrated.
The FPGA is programmed using the JTAG interface. The
board maintainer must provide accessors to drive the
JTAG signals TCK, TMS, TDI and to get the value of the
input signal TDO.
