Commit 8e729e3b521d9 "intel-hda: Fix reset of MSI function" (applied to 1.1.1 as 0ec39075710) added a call to msi_reset() into intel_hda_reset() function. But this function is called not only from PCI bus reset method, but also from device init method (intel_hda_set_g_ctl()), and there, we should not reset msi state. For this, split intel_hda_reset() into two halves, one common part with device reset, and one with msi reset, intel_hda_reset_msi(), which also calls the common part, for the bus method. This is only needed for 1.1.x series, since in 1.2+, MSI reset is called in proper places by the PCI code already.
