[Skiboot] [PATCH] struct p9_sbe_msg doesn't need to be packed

[Stewart Smith]

Only the reg member is sent anywhere (via xscom_write), so the structure
does not need to be packed.

Fixes GCC9 build problem:
hw/sbe-p9.c: In function ‘p9_sbe_msg_send’:
hw/sbe-p9.c:270:9: error: taking address of packed member of ‘struct p9_sbe_msg’ may result in an unaligned pointer value [-Werror=address-of-packed-member]
  270 |  data = &msg->reg[0];
      |         ^~~~~~~~~~~~
