platform-drivers-x86 for v5.1-1

Use MODULE_DEVICE_TABLE across several wmi drivers, keeping
 wmi_device_id and MODULE_ALIAS() declarations in sync. Add several
 Ideapad models to the no_hw_rfkill list. Add support for new Mellanox
 platforms, including new fan and LED functionality. Address Dell
 keyboard backlight change event and power button release issues. Update
 dell_rbu to use appropriate memory allocation mechanisms. Several small
 fixes and Ice Lake support for intel_pmc_core. Fix a suspend regression
 for Cherry Trail based devices in intel_int0002_vgpio. A few other
 routine fixes.
