Linus Walleij 252b0e790d dma-buf: heaps: Clear CMA highages using helper ...

Currently the CMA allocator clears highmem pages using
kmap()->clear_page()->kunmap(), but there is a helper
static inline in <linux/highmem.h> that does the same for
us so use clear_highpage() instead of open coding this.
