lib: s390x: sclp: Add line mode input handling

Time to add line-mode input so we can use input handling under LPAR if
there's no access to a ASCII console.

Line-mode IO is pretty wild and the documentation could be improved a
lot. Hence I've copied the input parsing functions from Linux.

For some reason output is a type 2 event but input is a type 1
event. This also means that the input and output structures are
different from each other.

The input can consist of multiple structures which don't contain text
data before the input text data is reached. Hence we need a bunch of
search functions to retrieve a pointer to the text data.

lib: s390x: sclp: Add compat handling for HMC ASCII consoles

Without the \r the output of the HMC ASCII console takes a lot of
additional effort to read in comparison to the line mode console.

Additionally we add a console clear for the HMC ASCII console so that
old messages from a previously running operating system are not
polluting the console.

lib: s390x: add support for SCLP console read

Add a basic implementation for reading from the SCLP ASCII console. The goal of
this is to support migration tests on s390x. To know when the migration has been
finished, we need to listen for a newline on our console.

Hence, this implementation is focused on the SCLP ASCII console of QEMU and
currently won't work under e.g. LPAR.

s390x: lib: Move to GPL 2 and SPDX license identifiers

In the past we had some issues when developers wanted to use code
snippets or constants from the kernel in a test or in the library. To
remedy that the s390x maintainers decided to move all files to GPL 2
(if possible).

At the same time let's move to SPDX identifiers as they are much nicer
to read.

Also with smp CPUs have to compete for sclp. Let's add some locking,
so they execute sclp calls in an orderly fashion and don't compete for
the data buffer.
