tty/serial: omap: fix !wakeirq message
When wakeirq is not used/enabled, "no wakeirq for uart0" is output for
all TTY as the log message is generated before the port line is
initialized.
[ 0.802656] Serial: 8250/16550 driver, 4 ports, IRQ sharing enabled
[ 0.811700] omap_uart 44e09000.serial: no wakeirq for uart0
[ 0.812379] 44e09000.serial: ttyO0 at MMIO 0x44e09000 (irq = 88, base_baud = 3000000) is a OMAP UART0
[ 1.503622] console [ttyO0] enabled
[ 1.509836] omap_uart 48022000.serial: no wakeirq for uart0
[ 1.516118] 48022000.serial: ttyO1 at MMIO 0x48022000 (irq = 89, base_baud = 3000000) is a OMAP UART1
[ 1.527711] omap_uart 48024000.serial: no wakeirq for uart0
[ 1.533881] 48024000.serial: ttyO2 at MMIO 0x48024000 (irq = 90, base_baud = 3000000) is a OMAP UART2
[ 1.545324] omap_uart 481a6000.serial: no wakeirq for uart0
[ 1.551410] 481a6000.serial: ttyO3 at MMIO 0x481a6000 (irq = 60, base_baud = 3000000) is a OMAP UART3
[ 1.562946] omap_uart 481a8000.serial: no wakeirq for uart0
[ 1.569036] 481a8000.serial: ttyO4 at MMIO 0x481a8000 (irq = 61, base_baud = 3000000) is a OMAP UART4
Fix by moving wakeirq initialization, check, and dev_info() call to
after port line initialization and validation.
