drivers/lcd: ssd1306: separate lcd_dev_s setup to separate object. g_oleddev takes 1 KiB because framebuffer and was allocated to .data section because of lcd_dev_s function pointer setup. Move lcd_dev_s setup out, so that g_oleddev goes to .bss and avoid wasting ROM.

drivers/lcd: ssd1306: fix memory corruption caused by ssd1306_getrun(). ssd1306_getrun was writing one extra byte (with value 0) past target buffer when pixlen is multiple of 8. When pixlen was not multiple of 8, last byte of buffer was fully cleared, instead of modifying only the (pixlen % 8) bits of last byte.

STM32 and EFM32 SPI drivers adopted an incompatible conventions somewhere along the line. The set the number of bits to negative when calling SPI_SETBITS which had the magical side-effect of setting LSB first order of bit transmission. This is not only a hokey way to pass control information but is supported by no other SPI drivers.
...
This change three things: (1) It adds HWFEAT_LSBFIRST as a new H/W feature. (2) It changes the implementations of SPI_SETBITS in the STM32 and EFM32 derivers so that negated bit numbers are simply errors and it adds the SPI_HWFEATURES method that can set the LSB bit order, and (3) It changes all calls with negative number of bits from all drivers: The number of bits is now always positive and SPI_HWFEATUREs is called with HWFEAT_LSBFIRST to set the bit order.

* This driver supports the 'I2C lcd backpack' design that is based on the PCF8574 io expander. There's a myriad of different vendors of such, but they are principally the same, save wiring and minor features like jumpers for I2C addresses. This driver supports known and unknown variants.
...
* The interface board supports HD44780-based LCD modules up to 4x32, and this driver accommodates all those formats.
