[PATCH] powerpc/ps3: fix ps3.h kernel-doc warnings

[Randy Dunlap]

Eliminate all kernel-doc warnings in ps3.h:
- add one missing struct member description
- add one missing function short description
- correct one enum name typo
- change several incomplete kernel-doc comments to plain "/*" comments

Examples:

Warning: arch/powerpc/include/asm/ps3.h:96 struct member 'dev' not
 described in 'ps3_dma_region'
Warning: arch/powerpc/include/asm/ps3.h:408 missing initial short
 description on line: * ps3_system_bus_set_drvdata -
Warning: arch/powerpc/include/asm/ps3.h:473 Enum value
 'PS3_LPM_TB_TYPE_INTERNAL' not described in enum 'ps3_lpm_tb_type'
Warning: arch/powerpc/include/asm/ps3.h:473 Excess enum value
 '@PS3_LPM_RIGHTS_USE_TB' description in 'ps3_lpm_tb_type'

You sent a V2 with the same subject some time ago, see 
https://patchwork.ozlabs.org/project/linuxppc-dev/patch/20251129183636.1893634-1-rdunlap@infradead.org/

Is this patch something else, does it superseeds V2, or is it a wrong 
resend of V1 ?

Yup, it's a wrong resend of v1. It means that my patch tracking system
failed me. Sorry about that.

Ok so I reject that one.
