Subject: [PATCH] spi: pxa2xx: Replace header inclusions by forward
 declarations

When the data structure is only referred by pointer, compiler may not need
to see the contents of the data type. Thus, we may replace header inclusions
by respective forward declarations. Due to above add missed headers as well.
