Embedded flash can have user signature area on SAMv7. This is a 512
bytes large page whose data are not erased by asserting ERASE pin or by
software ERASE command.
This commit adds arch to board interface for this area. It is possible
to perform read, write and erase operation. SAMV7_USER_SIGNATURE option
has to be set in the configuration.

By default U(S)ART clocks are enabled in sam_lowput.c but
configuration check from sam_config.h may override USART configuration
and prevent clocks from been enabled.

Make channels synchronous (i.e. share the same timebase) with the help
of SAMV7_PWMx_CHy_SYNC defines. All the channels share the same
timebase of channel 0, so this channel must be defined too.

With CONFIG_MMCSD_MULTIBLOCK_LIMIT not set. (No limit)
The DMA driver would overwrite the internal buffer.
By adding CONFIG_ARCH_HAVE_SDIO_PREFLIGHT and
CONFIG_FAT_DMAMEMORY we can insure alignment and
maximize performance using no CONFIG_MMCSD_MULTIBLOCK_LIMIT
Option CONFIG_SENSORS_QENCODER might be configured even if SAMv7 qencoder
over timer counter is not used (for example encoder over GPIO is selected
with CONFIG_SAMV7_GPIO_ENC). This can cause compile warnings, also build
of sam_qencoder.c file is unnecessary in that case.
New hidden option CONFIG_SAMV7_QENCODER is added and automatically
selected if at least one timer counter is enabled for qencoder. Build
is triggered on this option.

PWMx_CHy_LONLY options have been added to Kconfig, too.
If LONLY is selected, it's not possible to use complementary outputs.
If LONLY is not selected, it's possible to use H or complementary
output. If configured correctly with cpol and dcpol attributes,
a H-like behaviour can be achieved. May be useful when you run out
of free MCU pins.

The FPU is not affected by any security configuration.
Thus, it appears as not present in PERIPHID[n].PERM

The SAMV7's qencoder driver now supports the GETINDEX ioctl call
which does not reset the internal Timer/Counter and returns
the current position, position of the last index and the number
of captured indexes to a struct qe_index_s pointer. Because the
SAMV7's timers are 16bit, the extension to 32 bits must be done.
Select CONFIG_SAMV7_QENCODER_ENABLE_GETINDEX in the Kconfig to
enable this functionality.
This driver does not obey the instructions given in the ATSAMV7
2023 datasheet because the recommended trigger resets the internal
counter which is not desired. Instead, a capture into capture A
and capture B registers is used. This way if an event happens
(the rising edge of the index signal), the current counter's value
is captured.

According to the qemu source code, hw/arm/virt.c.
The secure memory of the ARM Virt board is [0xe000000~0xf000000]
and the non-secure memory is configured as [0x40000000~0xffffffff].
We made the following adjustments based on the above virt board configuration
