Bring back FW_TEXT_START as an optional parameter to allow users
explicitly specify compile time address for loading debug symbols.
When not specified, the FW_TEXT_START is assumed to be 0.

When using `PLATFORM=generic` defaults, the kernel is loaded at
`FW_JUMP_ADDR`, and the FDT is loaded at `FW_JUMP_FDT_ADDR.
Therefore, the maximum kernel size before `FW_JUMP_FDT_ADDR` must
be increased is `$(( FW_JUMP_FDT_ADDR - FW_JUMP_ADDR ))`.
The example calculation assumes `rv64`, and is wrong to boot
(off by 0x200000). Fix it and update it for the general case.

Since
commit 9c07c513aa9b ("firmware:Remove FW_PAYLOAD_FDT_PATH compile-time option"),
the section where FDT would be embedded in has changed from *.text* to *.rodata*,
but some places in fw_payload.md and fw.md are still *.text*.
This patch updates the document.

We update all documentation files to:
1) Remove references to platform specific config.mk file since it is
has been removed.
2) Add details about platform specific configs/defconfig and Kconfig
files mandatory for each platform.
3) Add required packages in top-level README.md
4) Fix typo releated to object.mk in docs/platform/platform.md

With QEMU v4.2 RISC-V changes to improve the emulation fidelity
of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10 / Linux
kernel v5.3 images built for the SiFive HiFive Unleashed board
can be used out of the box without any special hack. Hence there
is no need for us to continue supporting such a special target in
OpenSBI. Going forward, sifive/fu540 platform can be used on both
real hardware and QEMU 'sifive_u' machine.

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..
