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. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com>
