[PATCH] powerpc/pseries: Define __u{8,32} types in papr_hvpipe_hdr struct

[Haren Myneni]

Fix the the following build errors with CONFIG_UAPI_HEADER_TEST:

./usr/include/asm/papr-hvpipe.h:16:9: error: unknown type name 'u8'
   16 |         u8 version;
./usr/include/asm/papr-hvpipe.h:17:9: error: unknown type name 'u8'
   17 |         u8 reserved[3];
./usr/include/asm/papr-hvpipe.h:18:9: error: unknown type name 'u32'
   18 |         u32 flags;
./usr/include/asm/papr-hvpipe.h:19:9: error: unknown type name 'u8'
   19 |         u8 reserved2[40];
