powercap: RAPL: Fix CONFIG_IOSF_MBI dependency
After commit 3382388d7148 ("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.
