drivers: sh: Restore legacy clock domain on SuperH platforms
CONFIG_ARCH_SHMOBILE is not only enabled for Renesas ARM platforms (which are DT based and multi-platform), but also on a select set of Renesas SuperH platforms (SH7722/SH7723/SH7724/SH7343/SH7366). Hence since commit 0ba58de231066e47 ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI"), the legacy clock domain is no longer installed on these SuperH platforms, and module clocks may not be enabled when needed, leading to driver failures. To fix this, add an additional check for CONFIG_OF. Fixes: 0ba58de231066e47 ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI").
