dmascc: add CONFIG_VIRT_TO_BUS dependency
Many architectures don't define virt_to_bus() any more, as drivers
should be using the dma-mapping interfaces where possible:
In file included from drivers/net/hamradio/dmascc.c:27:
drivers/net/hamradio/dmascc.c: In function 'tx_on':
drivers/net/hamradio/dmascc.c:976:30: error: implicit declaration of function 'virt_to_bus'; did you mean 'virt_to_fix'? [-Werror=implicit-function-declaration]
976 | virt_to_bus(priv->tx_buf[priv->tx_tail]) + n);
| ^~~~~~~~~~~
arch/arm/include/asm/dma.h:109:52: note: in definition of macro 'set_dma_addr'
109 | __set_dma_addr(chan, (void *)__bus_to_virt(addr))
| ^~~~
Add the Kconfig dependency to prevent this from being built on
architectures without virt_to_bus().
Fixes: bc1abb9e55ce ("dmascc: use proper 'virt_to_bus()' rather than casting to 'int'")
