    powercap: RAPL: Fix CONFIG_IOSF_MBI dependency · 4658fe81
    Zhang Rui authored
    After commit 3382388d ("intel_rapl: abstract RAPL common code"),
    accessing to IOSF_MBI interface is done in the RAPL common code.
    
    Thus it is the CONFIG_INTEL_RAPL_CORE that has dependency of
    CONFIG_IOSF_MBI, while CONFIG_INTEL_RAPL_MSR does not.
    
    This problem was not exposed previously because all the previous RAPL
    common code users, aka, the RAPL MSR and MMIO I/F drivers, have
    CONFIG_IOSF_MBI selected.
    
    Fix the CONFIG_IOSF_MBI dependency in RAPL code. This also fixes a build
    time failure when the RAPL TPMI I/F driver is introduced without
    selecting CONFIG_IOSF_MBI.
    
    x86_64-linux-ld: vmlinux.o: in function `set_floor_freq_atom':
    intel_rapl_common.c:(.text+0x2dac9b8): undefined reference to `iosf_mbi_write'
    x86_64-linux-ld: intel_rapl_common.c:(.text+0x2daca66): undefined reference to `iosf_mbi_read'
    
    Reference to iosf_mbi.h is also removed from the RAPL MSR I/F driver.
