Two non-subsequent PTEs can be mapped to subsequent paddrs. In this
case, walk_pte will erroneously merge them.
Enforce the split up, by tracking the virtual base address.
Let's say we have the mapping:
0x81200000 -> 0x89623000 (4K)
0x8120f000 -> 0x89624000 (4K)
Before, walk_pte would have shown:

The Linux kernel parses the ISA extensions from "riscv,isa" DT
property. It used to parse only the single letter base extensions
until now. A generic ISA extension parsing framework was proposed[1]
recently that can parse multi-letter ISA extensions as well.
Generate the extended ISA string by appending the available ISA extensions
to the "riscv,isa" string if it is enabled so that kernel can process it.

This commit also removes all reserved/dropped single-letter "extensions"

- "J": Not going to be a single-letter extension (misa.J is reserved).

The RISC-V specification states that:
"Supervisor-level external interrupts are made pending based on the
logical-OR of the software-writable SEIP bit and the signal from the
external interrupt controller."
We currently only allow either the interrupt controller or software to
set the bit, which is incorrect.
This patch removes the miclaim mask when writing MIP to allow M-mode
software to inject interrupts, even with an interrupt controller.
We then also need to keep track of which source is setting MIP_SEIP. The
final value is a OR of both, so we add two bools and use that to keep
track of the current state. This way either source can change without
losing the correct value.

Replace the boilerplate code to declare CPU QOM types
and macros, and forward-declare the CPU instance type.

While CPUState is our interface with generic code, CPUArchState is
our interface with target-specific code. Use CPUArchState as an
abstract type, defined by each target.

These target-specific files use the target-specific CPU state
but lack to include "cpu.h"; i.e.:
../target/riscv/pmp.h:61:23: error: unknown type name 'CPURISCVState'
void pmpcfg_csr_write(CPURISCVState *env, uint32_t reg_index,
^
../target/nios2/mmu.h:43:18: error: unknown type name 'CPUNios2State'
void mmu_flip_um(CPUNios2State *env, unsigned int um);
^
../target/microblaze/mmu.h:88:19: error: unknown type name 'CPUMBState'; did you mean 'CPUState'?
uint32_t mmu_read(CPUMBState *env, bool ea, uint32_t rn);
