2e338c77ea gpu: nvgpu: remove duplicate \n from log messages
nvgpu_log/info/warn/err() internally add a \n to the end of the message.
Hence, callers should not include a \n at the end of the message. Doing
so results in duplicate \n being printed, which ends up creating empty
log messages. Remove the duplicate \n from all err/warn messages.

Remove gk20a_platform dependencies from gk20a.h. This makes
gk20a_platform a Linux platform specific data structure. Add #include
for platform_gk20a.h in the source files that still depend on Linux.

e13d0723f6 gpu: nvgpu: Use correct register for ROM control
We access ROM control register with xve_writel, but we also
add the base register address. This leads to adding the base
address twice, and the access goes to wrong register.

b3e1ce04b9 gpu: nvgpu: Put debugfs dependencies inside #ifdef
Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This
includes some functions in allocators that were used only for
debugging.

Remove include of linux/debugfs.h on files that do not deal with
debugfs.

linux/debugfs.h implicitly included linux/fs.h, which we relied on.
Add explicit include of linux/fs.h for all files where this is the
case.
