[Buildroot] [PATCH 17/19] package/cryptodev: convert to the virtual-package infrastructure

[Yann E. MORIN <yann.morin.1998@free.fr>]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

Since this package is implemented via a choice rather than the usual
separate-package providers, we only need BR2_PACKAGE_HAS_CRYPTODEV
to be always defined when the 'cryptodev' package is selected.
