Subject: [PATCH] device-tablet-x86uefi: new device (MR 1913)

This is a generic package for devices which use x86_64 CPU and 32-bit
EFI. Most distributions don't provide installation for 32-bit EFI, so
installation is not user-friendly.

Actually, these tablets deserve device-specific packages (I am going to
make ones for ASUS VivoTab Note 8 and ASUS Transformer Book T100TA), but
this one includes basic functions and can be booted on any 32-bit EFI
tablet with disabled secure boot and missing device-specific package.
I guess 32-bit EFI with 64-bit CPU is Intel's "feature" and AMD doesn't
have such stuff, so this package will be installed only on devices with
Intel CPU, unlike device-tablet-x64uefi which can be installed on any
x86_64 PC. So i decided to enable some Intel specific things (userspace
GPU stuff and alsa-ucm-conf).

I used for reference device-tablet-x64uefi and
device-trekstor-surftabduow1 packages. This package also can be used as
a reference for device-specific ones.
