Paul Sokolovsky 2681199c29 drivers: serial: uart_sam: Fix typo in param name.
The refactor to add callback user data param in 57286afd, contained
typo just for this driver. It sneaked past the PR CI due to the fact
that issue affected just a couple of platforms, and we select just
a few of them randomly for PR CI (vs full CI).

Paul Sokolovsky 57286afdd6 drivers: uart: Allow to pass arbitrary user data to irq callback
Zephyr UART drivers offer very low-level functionality. Oftentimes,
it would be useful to provide higher-level wrappers around UART
device which would offer additional functionality. However, UART
driver irq callback routine receives just a pointer to (low-level)
UART device, and it's not possible to get to a wrapper structure
(without introducing expensive external mapping structures). This
is an indirect reason why the current UARt wrappers - uart_pipe,
console - are instantiated statically just for one underlying UART
device and cannot be reused for multiple devices.

Solve this by allowing to pass an arbitrary user data to irq
callback, set by new uart_irq_callback_user_data_set() function.
Existing uart_irq_callback_set() keeps setting a callback which
will receive pointer to the device.

While public API maintains compatibility, drivers themselves need
to be updated to support arbitrary user data storage/passing (as
legacy uart_irq_callback_set() functionality is now implemented in
terms of it).

Kumar Gala ccad5bf3e3 drivers: convert to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

Piotr Mienkowski 34c16ad2f7 drivers: Add Atmel SAM serial (UART) driver
Added serial (UART) driver for Atmel SAM MCU family.

Note:
- Error handling is not implemented
- The driver works only in polling mode, interrupt mode is
  not implemented.

Tested on Atmel SMART SAM E70 Xplained board
