[PATCHv2] crypto: inside-secure - Fix unused variable warning when CONFIG_PCI=n

[Pascal van Leeuwen <pascalvanl@xxxxxxxxx>]

This patch fixes an unused variable warning from the compiler when the
driver is being compiled without PCI support in the kernel.

changes since v1:
- capture the platform_register_driver error code as well
- actually return the (last) error code
- swapped registration to do PCI first as that's just for development
  boards anyway, so in case both are done we want the platform error
  or no error at all if that passes
- also fixes some indentation issue in the affected code
