serial: 8250: 8250_omap: make a const array static, makes object smaller

Browse source 
Don't populate the const array k3_soc_devices on the stack but instead it
static. Makes the object code smaller by 44 bytes:

Before:
   text    data     bss     dec     hex filename
  31628    5609     128   37365    91f5 drivers/tty/serial/8250/8250_omap.o

After:
   text    data     bss     dec     hex filename
  31520    5673     128   37321    91c9 drivers/tty/serial/8250/8250_omap.o
Reduction of 44 bytes

(gcc version 10.3.0)
