As per the current SBI specification, sbi_getc should return
an int instead of char.
In case of FIFO is empty, return -1 as per the specification.

Makes for easy and quick build-run one-stop command.
For now only added for qemu targets. It can be added for
any platform having simulator/emulator (such as QEMU).

This patch introduces following optional PLATFORM options:
PLATFORM_RISCV_XLEN -> RISC-V register width
PLATFORM_RISCV_ABI -> RISC-V GCC ABI
PLATFORM_RISCV_ISA -> RISC-V GCC ISA string
PLATFORM_RISCV_CODE_MODEL -> RISC-V GCC Code Model
If the above options are not provided by platform config.mk
or by command-line parameters then:
1. PLATFORM_RISCV_XLEN will be determined using toolchain
capability
2. PLATFORM_RISCV_ABI, PLATFORM_RISCV_ISA, and
PLATFORM_RISCV_CODE_MODEL is set to value best suited for
generic libsbi.a
As a result of these optional PLATFORM options, the
platform-cflags-y and platform-asflags-y is further
simplified for platform config.mk.

Both FW_JUMP_ADDR and FW_PAYLOAD_OFFSET, should be:
1. 4MB aligned for 32bit system
2. 2MB aligned for 64bit system
Explicitly specify the above details in config.mk comments
for template platform.

In order to support 32-bit guests move the start address to a 4MB
allignment. As 64-bit kernels have a requirement on being 2MB alligned
let's just make this the default for both 32 and 64 bit kernels.

The QEMU virt machine can be either 32 or 66 bit. Don't hard code the
CPU bit length and instead let the compiler determine it.
