stm32_uart: rename exported structure and add secure flag

Rename structure console_pdata into stm32_uart_pdata as it will
be exported over the platform and should not use such a generic
naming.

This change adds a secure flag to the UART device instance for
used to get the appropriate virtual address when required.
An UART bus could be used by the secure world in secure mode or
in non-secure mode. A bus to a secure element likely mandates
secure hardening of the UART. A debug console over a non-secure
UART link may require the UART resources to be assigned to the
non-secure world.
