chao an c6591c0f49 driver/serial: remove return value of up_putc() 
modify the prototype of up_putc(): remove the return value

The architecture code does not care about the return value of up_putc(), so removing it saves two statements:

Before:                                                    After:
de4c: e52de004  push  {lr}    @ (str lr, [sp, #-4]!)    |  de4c: e52de004  push  {lr}    @ (str lr, [sp, #-4]!)
de50: e24dd014  sub sp, sp, #20                         |  de50: e24dd014  sub sp, sp, #20
de54: e58d0004  str r0, [sp, #4]                        |  de54: e58d0004  str r0, [sp, #4]
de58: e30030f8  movw  r3, #248  @ 0xf8                  |  de58: e30030f8  movw  r3, #248  @ 0xf8
de5c: e3423000  movt  r3, #8192 @ 0x2000                |  de5c: e3423000  movt  r3, #8192 @ 0x2000
de60: e58d300c  str r3, [sp, #12]                       |  de60: e58d300c  str r3, [sp, #12]

de68: e59d000c  ldr r0, [sp, #12]                       |  de68: e59d000c  ldr r0, [sp, #12]

de70: e59d3004  ldr r3, [sp, #4]                        |  de70: e28dd014  add sp, sp, #20
de74: e1a00003  mov r0, r3                              |  de74: e49df004  pop {pc}    @ (ldr pc, [sp], #4)
de78: e28dd014  add sp, sp, #20                         |
de7c: e49df004  pop {pc}    @ (ldr pc, [sp], #4)        |
