Use GENMASK() to generate the masks of device type and device id,
fixing compilation errors due to the sign extension when using
older versions of GCC (such as is 7.5):
In function ‘kvm_vm_ioctl_set_device_addr.isra.38’,
inlined from ‘kvm_arch_vm_ioctl’ at arch/arm64/kvm/arm.c:1454:10:
././include/linux/compiler_types.h:354:38: error: call to ‘__compiletime_assert_599’ \
declared with attribute error: FIELD_GET: mask is not constant
_compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
Fixes: 9f968c9266 ("KVM: arm64: vgic-v2: Add helper for legacy dist/cpuif base address setting")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
