RDMA/hfi1: Depend on !UML

Both hfi1 and UML depend on x86_64, this can trigger build errors.
This driver must depends on !UML because it accesses x86_64
features that are not supported by UML.

treewide: replace '---help---' in Kconfig files with 'help'

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

IB/hfi1: Remove HFI1_VERBS_31BIT_PSN option

Remove HFI1_VERBS_31BIT_PSN Kconfig option leaving only 31-bit PSNs
available. The option was implemented in the early days of the driver
and is no longer needed.

IB/hfi1: Disable by default

There is a strict policy in the Linux kernel that new drivers must be
disabled by default. Hence leave out the "default m" line from Kconfig.

IB/hfi1: Move driver out of staging

The TODO list for the hfi1 driver was completed during 4.6. In addition
other objections raised (which are far beyond what was in the TODO list)
have been addressed as well. It is now time to remove the driver from
staging and into the drivers/infiniband sub-tree.
