bcma: make OF code more generic (not platform_device specific)
OF allows not only specifying platform devices but also describing devices on standard buses like PCI or USB. This change will allow reading info from DT for bcma buses hosted on PCI cards. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

y P-state mode, where this setting has no effect. Linux' intel_pstate driver does not require ACPI/CPPC to enable HWP, and so it runs in HWP mode, exposing this incorrect BIOS configuration. There are several ways to address this problem. First, Linux can also run in legacy P-state mode on this system. As intel_pstate is how Linux enables HWP, booting with "intel_pstate=disable" will run in acpi-cpufreq/ondemand legacy p-state mode. Or second, the "performance" governor can be used with intel_pstate, which will modify HWP.EPP to 0. Or third, starting in 4.10, the /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference attribute in can be updated from "balance_power" to "performance". Or fourth, apply this patch, which fixes the erroneous setting of MSR_IA32_POWER_CTL BIT_EE on this model, allowing the default configuration to function as designed.
