The hartid parameter in IRQCHIP callbacks of sbi_platform
is not required because current hartid can be determined
using sbi_current_hartid() API.

The source_hart and hartid parameter is really not required in
IPI callbacks of sbi_platform because current hartid can always
be obtained by calling sbi_current_hartid() API.

We don't need to pre-enable MSIP in MIE CSR when
calling sbi_init() from firmware. This patch updates
documentation accordingly.

Instead of having separate timer_init() hooks for cold and
warm boot, this patch updates struct sbi_platform to have just
one timer_init() hook. The type of boot (cold or warm) is now
a boolean flag parameter for the updated timer_init() hook.

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.
