The options defined in config.mk can be specified in objects.mk of each
platform so let us remove config.mk from all platforms.

Let us move SiFive platform overrides for FU540 and FU740 into a separate
directory so better maintainability. Other SoC vendors can also create
their own directory under platform/generic.

Instead of having platform override module list hard-coded in the C source,
we generate it using carray.sh at compile-time.

Instruction TLB can fail to respect a non-global SFENCE thus we need to
flush the TLB using SFENCE.VMA x0, x0

We need to override the remote TLB flush range limit for SiFive FU540
so we add platform override to achieve this.

We add generic FDT based platform support which provides platform
specific functionality based on the FDT passed by previous booting
stage.
By default, the generic FDT platform makes following assumptions:
1. platform FW_TEXT_START is 0x80000000
2. platform features are default
3. platform stack size is default
4. platform has no quirks or work-arounds
The above assumptions (except 1) can be overridden by adding special
platform callbacks which will be called based on the FDT root node
compatible string.
By default, we compile OpenSBI generic platform as follows:
$ make PLATFORM=generic
For a non-standard FW_TEXT_START, we can compile OpenSBI generic
platform as follows:
$ make PLATFORM=generic FW_TEXT_START=<non_standard_text_start>
