Move the code to mark the TSC as reliable from sme_early_init() to snp_secure_tsc_init(). The only reader of TSC_RELIABLE is the aptly named check_system_tsc_reliable(), which runs in tsc_init(), i.e. after snp_secure_tsc_init(). This will allow consolidating the handling of TSC_KNOWN_FREQ and TSC_RELIABLE when overriding the TSC calibration routine.
