We generally don't get misaligned load/store traps from Linux/U-Boot
compiled using GCC 8.2 or higher but this is not true with older
GCC toolchains. To tackle this we add misaligned load/store trap
handling adopted from BBL sources but much more simpler.
(Note: BBL sources can be found at https://github.com/riscv/riscv-pk.git)

The hart_count and hart_stack_size information is already available
in "struct sbi_platform" so we use that instead of depending on
PLAT_HART_COUNT and PLAT_HART_STACK_SIZE.

As of now, uboot doesn't have support for SMP.
Moreover, unleashed board has a E51 hart which
doesn't not support S mode.
We should only boot only 1 non-zero hart.

Cleanup sbi_hart_boot_nexti() code, adding messages for clarity and
rename the function to sbi_hart_switch_mode() to reflect what the
function actually does.

Allow a platform to report its supported features in more details.
The new features defined are:
* SBI_PLATFORM_HAS_PMP
* SBI_PLATFORM_HAS_SCOUNTEREN
* SBI_PLATFORM_HAS_MCOUNTEREN
In addition, define the macro SBI_PLATFORM_DEFAULT_FEATURES as the set
of features that are generally expected to be supported by a Linux
capable platform.
Operations touching the features controlled with these falgs are not
executed if the platform does not set the corresponding feature flags.
