crypto: picoxcell - Remove PicoXcell driver

Browse Source 
PicoXcell has had nothing but treewide cleanups for at least the last 8
years and no signs of activity. The most recent activity is a yocto vendor
kernel based on v3.0 in 2015.

This option enables support for the hardware offload engines in the
Picochip picoXcell SoC devices. Select this for IPSEC ESP offload
and for 3gpp Layer 2 ciphering support.
Saying m here will build a module named picoxcell_crypto.
