[ARM] pxa: Fix PXA27x suspend type validation, remove pxa_pm_prepare()

Browse Source 
pxa_pm_prepare() tried to validate the suspend method type.  As
noted in previous commits:
	eb9289eb20df6b54214c45ac7c6bf5179a149026
	9c372d06ce9ddf65e1393f9ea22a6d6bd5f96b42
	e8c9c502690efd24b7055bf608e7a3c34216848b

the checking of the suspend type in the 'prepare' method is the
wrong place to do this; use the 'valid' method instead.  This
means that pxa_pm_prepare() can be entirely removed.
