Zhang Rui 4864c82cb8 powercap: RAPL: Fix CONFIG_IOSF_MBI dependency
[ Upstream commit 4658fe81b3 ]

After commit 3382388d71 ("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.
