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.

Initialize row_index to avoid a compile warning.
The warning seems incorrect, as row_index is initialized in the first
interation of the loop, but the overhead of initializing it is trivial,
so we may as well just do it.

Obviously, everyone knows that there are 8 bits per byte, so
there isn't a lot of magic happening, per se, but it's also
helpful to clearly denote where the magic number 8 is referring
to the number of bits in a byte.
Occasionally, 8 will refer to a field size or offset in a
structure, MMR, or word. Occasionally, the number 8 will refer
to the number of bytes in a 64-bit value (which should probably
be replaced with `sizeof(uint64_t)`).
For converting bits to bytes, or vice-versa, let's use
`BITS_PER_BYTE` for clarity (or other appropriate `BITS_PER_*`
macros).

This reverts commit 206897658a.
We must keep the frame completion interrupt disabled until we send a new
frame to the eLCDIF, as the frame completion interrupt fires at each
vertical blank interval. If we keep it enabled, then the semaphore we
use to indicate the frame has been loaded by the eLCDIF will be posted
to when we do not have a frame queued, and calls to `display_write` will
return before the eLCDIF has actually loaded the new framebuffer.

Initial support for SSD1322 OLED display driver. Only 1 bit color mode is
supported.
Most options map directly to values documented in the datasheet,
except segments-per-pixel, which I had to add to support the Newhaven
NHD-2.7-12864WDW3. This is a slightly odd feature, but in practice
it is a lot nicer to support it in the driver, and since we're currently
remapping pixels anyway, it makes sense to implement here.
This driver also has a configurable buffer size for the pixel conversion.
By using a larger buffer, we can potentially use DMA for the SPI transfer.
The default is set to 8, which is the smallest value that supports
segments-per-pixel = 2
