HCL - Dell Precision 5540

[brokoli]

Installation

 - noexitboot and mapbs need to be commented out for the installation to work

 - BIOS has no option for legacy boot anymore, only UEFI

 - TPM 2.0 only

 - ... so no aem

Misc

USB-C Dockingstation from Dell works out of the box (WD19DC). 

Problems with suspend: After adding mem_sleep_default=deep to the kernel boot options it only works with Kernel Version 4.19.82 (not 81, 84 or 5.3.11, any hints to how I might be able to debug this are welcome!)
