kconfig: drivers: spi: Remove duplicated dependencies
The two redundant SPI dependencies are from 'source'ing a file within an
'if SPI' and then adding another 'depends on SPI' within it.
'if FOO' is just shorthand for adding depends on FOO to each item within
the 'if'. There are no "conditional includes" in Kconfig, so 'if FOO'
has no special meaning around a source. Conditional includes wouldn't be
possible, because an if condition could include (directly or indirectly)
forward references to symbols not defined yet.
Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.
