Guo Ren d1e0f7f25b utils/reset: Remove fdt_reset_thead 
In the past, we used fdt_reset_thead to help customers with prototype
verification. However, with the emergence of the Big-little SoC system,
it can no longer meet the demand. Therefore, we use zero_stage_boot
instead of fdt_reset_thead. It cleans up the opensbi code and ends the
disputation of reset_sample's dts.

This patch removes the fdt_reset_thead component and updates the related
doc.

T-HEAD C9xx Series Processors

The C9xx series processors are high-performance RISC-V architecture multi-core processors with AI vector acceleration engine.

For more details, refer T-HEAD.CN

To build the platform-specific library and firmware images, provide the PLATFORM=generic parameter to the top level make command.

Platform Options

The T-HEAD C9xx does not have any platform-specific compile options because it uses generic platform.

CROSS_COMPILE=riscv64-linux-gnu- PLATFORM=generic make

Here is the simplest boot flow for a fpga prototype:

(Jtag gdbinit) -> (zsb) -> (opensbi) -> (linux)

For more details, refer: zero stage boot
