There was a misalignment between Zephyr UART device numbering and
SoC UART IP. Device "UART_1" was mapped to IP USART_2, which could
be confusing for user.
This commit allows to align "UART_1" to IP USART_1.
Change is propagated to all STM32F103RB/STM32F401RE based boards and
respective pinmux drivers

Replace the use of a hardwired temporary register in the irq_lock()

The cortex-m4 irq_lock() implementation uses a movs instruction, thus
clobbering the condition code, but does not include the clobber in the
asm clobber list. This is a bug in the situation where the compiler
schedules a live condition code over the inline lock instructions.
Since the irq_lock() implementation does not need to kill the CC we
simply switch to mov from movs.
Take the opportunity to drop the unnecessay .n and let the assembler
choose an appropriate encoding.
This fixes a bug found by inspection, it has not actually been
observed in real code.

This patch fixes RX overflow error in the k64 SPI driver.
Jira: ZEP-1351
Jira: ZEP-1352
Several circumstances lead to an RX overflow:
The RFOF_RE (RX fifo overflow) must not be set as default.
The flag is only set when rx_buf is available. Also it must
be checked inside spi_k64_isr whether RFOF_RE has been set or not.
If the rx_buf is not available and the incoming data
should be ignored, then MCR_ROOE need to be set.
Since it is not possible to change the MCR register
during the transfer, RX fifo must be emptied
if rx_buf_len < tx_buf_len.
The driver also uses spi_data.xfer_len now,
the variable was already defined. Now, transfers are also
possible if tx_buf_len < rx_buf_len (e.g. read slave device register).
spi_k64_push_data has been adjusted accordingly.
The patch simplifies the handling of interrupts.
The interrupts are also switched off in the event of an error.
The patch also fixes a few coding style issues.
