Use a more neutral term more representative of this payload intent.

Add rules to compile dts files into dtb files using the device tree
compiler (dtc). A platform can specify the DTS file to compile using
the platform-dtb-y variable. The flattened device tree binary file to be
used for building the final polatform firmware can be specified using
the new FW_PAYLOAD_FDT firmware configuration option to point to the
automatically compiled FDT file. Using the existing FW_PAYLOAD_FDT_PATH
configuration option is still possible and will take precedence over
the FW_PAYLOAD_FDT definition.

The firmware payload offset defined by FW_PAYLOAD_OFFSET must
specify a value large enough so the the payload does not overlap
with the base firmware data, bss and text. For platforms without
any strong requirement on the payload address, introduce the
FW_PAYLOAD_ALIGN build parameter to automatically place the payload
right after the base firmware at an address aligned with the defined
value.
Either FW_PAYLOAD_OFFSET or FW_PAYLOAD_ALIGN should be defined by a
platform configuration. If both FW_PAYLOAD_OFFSET and FW_PAYLOAD_ALIGN
are defined by a platform, FW_PAYLOAD_OFFSET has precedence and is
used for building the final firmawre image.
Using FW_PAYLOAD_ALIGN=4096 with the Kendryte platform rather than
the abitrary FW_PAYLOAD_OFFSET=0x10000 value reduces the final
firmware image size by about 20KB.
Add a description of the FW_PAYLOAD_ALIGN configuration parameter in the
fw_payload documentation file as well. And while at it, also fix
various grammar and style issues in that file..

We use recently added separate dummy payload for FW_PAYLOAD
when FW_PAYLOAD_PATH is not specified.

This patch renames "blob" to "firmware" everywhere for better
and intutive naming.
