[PATCH RFC v6 5/7] ipmi: ls2k: adjust dependency to its mfd driver

[Miao Wang <shankerwangmiao@gmail.com>]

There is functional dependency between the IPMI driver and its mfd
driver. Previously, the dependency was set to "select" from
IPMI_LS2K to MFD_LS2K_BMC_CORE. However, the ipmi driver is actually
compiled as a part of the ipmi_si module, and IPMI_LS2K is a bool
option. Therefore, the dependency "select" will force the mfd driver
to be compiled built-in when the ipmi driver is built as a module. This
is not desirable. This patch fixes this by declaring a conditional
dependency from IPMI_SI to MFD_LS2K_BMC_CORE if IPMI_LS2K is selected.
This will allow the mfd driver to be compiled as a module if the ipmi
driver is built as a module. The adjustment to Kconfig for the mfd
driver will be introduced in the later patch in this series.

Fixes: d46651d4e3c0 ("ipmi: Add Loongson-2K BMC support")
