As discussed with karlp on irc the devices.data file should not contain
gcc specific command line options.
For that reason the command line options for gcc are now generated from
the variables CPU and FPU by the rules in the mk directory.
This breaks the genlink tests.
genlink: simplified devices.data
devices.data already had the information about the family name.
By using the first field (by the pattern used to match it) as family name information that data doesn't
have to be provided explicitly. The same data is used to generate the
CPPFLAGS, such as -DSTM32F1
The architectures block of the devices.data file was redundant.
genlink-config.mk uses family and subfamily to figure out which libopencm3
variant actually exists.
f7 has -mfpu=fpv5-sp-d16 in the lib makefile, devices.data should have
the same setting.
l0 is a cortex m0+, not a cortex m0, and uses cortex-m0plus in the
library makefile, and should have the same setting in the devices.data
file.
Most changes are noise from doxygen.
Readme udpated to explain newer FP_FLAGS for m7
stm32f7 library is skipped if the toolchain doesn't support it yet.
Correct memory sizes in ld/devices.data for:
* stm32f3[01]3?c from RAM=48K to RAM=40K.
* stm32f303?b from RAM=40K to RAM=32K.

These devices have 32kiB RAM and 256kiB flash and are otherwise
register compatible with the f373x8 and f373xc devices.

in ARCH, there are all -m flags (will be expanded into ARCH_FLAGS in Makefile)
in DEFS, there are all -D flags (will be expanded into DEFS in Makefile)
in LIB, there are all -l flags (will be expanded into LIBNAME in Makefile)
If no MODE option specified, the generator behaves as in previous version.
This makes possibility for the script to append the definitions to CFLAGS
and LDFLAGS, and with the feature of disabling of -D prependation it will
make possible to generate ARCH_FLAGS generic to each specific chip.
