riscv: Add a reset_cpu() function

The current do_reset() is called from a command context. Add a function
which can be used from anywhere, as is done on ARM. Adjust do_reset()
to call it.

Note that reset_cpu() is normally provided by SYSRESET so make this
declaration conditional on that being disabled.

riscv: Remove common.h usage

We can remove common.h from most cases of the code here, and only a few
places need an additional header instead.

Revert "riscv: Allow use of reset drivers"

This reverts commit 958a3f464c7f8ef7e10db9feb663e9e80445ce2f.

A more appropriate change below is already in mainline.
Commit fd31e4fd184f ("riscv: Do not build reset.c if SYSRESET is on")

Revert this patch, so that U-Boot can be built successfully for

riscv: Allow use of reset drivers

Currently, one cannot use a reset driver on RISC-V. Follow the MIPS
example, and disable the default reset handler when the sysreset driver is
enabled.

command: Remove the cmd_tbl_t typedef

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

common: Move hang() to the same header as panic()

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

We don't have a reset method on any RISC-V board yet. Instead of
