IS25LPXXXD uses the same jedec-id as IS25LPXXX, but the latter has
an extended read register, similar to IS25WPXXX. This change will
attempt to read the extended read register to determine what the
appropriate initialization value for read register should be.

The implementation for erasing pages in the flash_sam.c driver
indicated a successful erase after exceeding the last page to be
erased successfully. Since the last page has no proceeding page,
the succeeded status was not set.
This fix switches around the status to be set as succeeded before
erase begins, to have the succeeded status cleared if page unlock
or erase fails.

Since the RA2L1 uses the macro "ICU_EVENT" instead of
"ELC_EVENT" (which is currently used) to input into
the IELSR register, the ek_ra2l1 board cannot assign
any interrupts for any driver.
This commit aim to correct the Event macro to input correct
value for IELSR register on all the Renesas SoC by using
"BSP_PRV_IELS_ENUM" macro.

Some flash devices enable entering the 4-byte address mode
by setting BIT(7) in a special register via a write instruction 0x17.

The BLE acronym is not an official description of Bluetooth
LE, and the Bluetooth SIG only ever refers to it as Bluetooth
Low Energy or Bluetooth LE, so Zephyr should as well.
This commit does not change any board or vendor specific
documentation, and the term BLE may still be used in those.
It will be up to the vendors to update it if they want,
since many of them are using the term BLE in their

XIP may indicate that the program is executed either in local memory
or flash. However, the SPI node is only used as a flash fetch device
when the program is executed in flash.
Therefore, optimize the related checks to ensure that when XIP is
enabled but the program is executed in local memory, the qspi flash
node can still be used.

The erase time varies between different SPI NOR flash chips.
Some have typical erase times in the 20-25ms range, at which point the
default 50ms poll interval means we get half the possible erase speed.
With slower memory, or larger erases, 50ms might not be a lot, but for
block erases, if we are unlucky we may end up polling just as the it's
about to finish erasing, and have to wait another poll interval.
