remoteproc: qcom: wcnss: Fix module autoload

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.

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

Before this patch:

$ modinfo drivers/remoteproc/qcom_wcnss.ko | grep alias
$

After this patch:

$ modinfo drivers/remoteproc/qcom_wcnss.ko | grep alias
alias:          of:N*T*Cqcom,pronto-v2-pilC*
alias:          of:N*T*Cqcom,pronto-v2-pil
alias:          of:N*T*Cqcom,pronto-v1-pilC*
alias:          of:N*T*Cqcom,pronto-v1-pil
alias:          of:N*T*Cqcom,riva-pilC*
alias:          of:N*T*Cqcom,riva-pil
