Subject: cpufreq: powernv: fix missing check of return value in
 init_powernv_pstates()

kmalloc() could fail, so insert a check of its return value. And
if it fails, returns -ENOMEM.

And remove (struct pstate_idx_revmap_data *) to fix coccinelle WARNING
by the way.

WARNING: casting value returned by memory allocation function to (struct
pstate_idx_revmap_data *) is useless.

Subject: cpufreq: davinci: move configuration to include/linux/platform_data

The header containing the configuration structure for davinci cpufreq
driver lives in mach-davinci/include/mach/. This is fine for now but
if we want to make davinci part of the multi_v5 build, no code external
to mach-davinci should include machine-specific headers.

Move the configuration structure to include/linux/platform_data.

While we're at it: convert the GPL-2.0 boilerplate to a proper SPDX
license identifier.
