soc: qcom: eud: Fix enable status for secure mode

Browse source 
Currently, the EUD driver performs the check if bootloaders
have already enabled the EUD hardware by doing a logical OR
of EUD_CSR_EUD_EN (non-secure) and EUD_EUD_EN2 (secure), even
if the driver is configured to work in secure mode, which is
incorrect. Hence, check the status of the EUD hardware by only
looking at the respective register for that particular mode.
