[PATCH] crypto: picoxcell - Fix module autoload for non-OF registration

[Javier Martinez Canillas]

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module if the device isn't registered via OF.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/crypto/picoxcell_crypto.ko | grep alias
alias:          of:N*T*Cpicochip,spacc-l2C*
alias:          of:N*T*Cpicochip,spacc-l2
alias:          of:N*T*Cpicochip,spacc-ipsecC*
alias:          of:N*T*Cpicochip,spacc-ipsec

After this patch:

$ modinfo drivers/crypto/picoxcell_crypto.ko | grep alias
alias:          of:N*T*Cpicochip,spacc-l2C*
alias:          of:N*T*Cpicochip,spacc-l2
alias:          of:N*T*Cpicochip,spacc-ipsecC*
alias:          of:N*T*Cpicochip,spacc-ipsec
alias:          platform:picochip,spacc-l2
alias:          platform:picochip,spacc-ipsec
