target/riscv: Remove the deprecated 'any' CPU type

Browse source 
The 'any' CPU is deprecated since commit f57d5f8004
("target/riscv: deprecate the 'any' CPU type"). Users
are better off using the default CPUs or the 'max' CPU.

RISC-V 'any' CPU type ``-cpu any`` (since 8.2)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The 'any' CPU type was introduced back in 2018 and has been around since the
initial RISC-V QEMU port. Its usage has always been unclear: users don't know
what to expect from a CPU called 'any', and in fact the CPU does not do anything
special that isn't already done by the default CPUs rv32/rv64.
After the introduction of the 'max' CPU type, RISC-V now has a good coverage
of generic CPUs: rv32 and rv64 as default CPUs and 'max' as a feature complete
CPU for both 32 and 64 bit builds. Users are then discouraged to use the 'any'
CPU type starting in 8.2.
