riscv: sifive: fix Kconfig errata warning

Browse Source 
The SOC_SIFIVE Kconfig entry unconditionally selects ERRATA_SIFIVE.
However, ERRATA_SIFIVE depends on RISCV_ERRATA_ALTERNATIVE, which is
not set, so SOC_SIFIVE should either depend on or select
RISCV_ERRATA_ALTERNATIVE. Use 'select' here to quieten the Kconfig
warning.

WARNING: unmet direct dependencies detected for ERRATA_SIFIVE
  Depends on [n]: RISCV_ERRATA_ALTERNATIVE [=n]
  Selected by [y]:
  - SOC_SIFIVE [=y]
