[PATCH] clk/at91: remove kernel-doc warnings in sama7g5.c

[Randy Dunlap]

Fix multiple kernel-doc warnings in sama7g5.c. There are several
enums and structs that were not identified as such.
There are also several anonymous structs (that scripts/kernel-doc
has problems with), so add struct names to them.

Fixes the following warnings:

drivers/clk/at91/sama7g5.c:39: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
 * PLL clocks identifiers

 * Generic clock description
drivers/clk/at91/sama7g5.c:339: warning: Function parameter or member 'ep_chg_id' not described in 'master_clock'

Some kernel-doc warnings are still printed, but they are all due to
problems in the kernel-doc script (if anyone is interested in playing
with some Perl :). These warnings are:

sama7g5.c:287: warning: Function parameter or member '{' not described in 'sama7g5_plls'
sama7g5.c:287: warning: Function parameter or member '' not described in 'sama7g5_plls'
