axi_jesd204_common/jesd204_up_common: Add event stats 

Add statistics for :
 - number of link enable events
 - number of interrupt events (regardless of mask)

0x0B0 0x2C0 Stats Control Register
  [0] - Write 1 to clear stat registers

0x0B1 0x2C4 Link Enable Stat Register
  [15:0] Number of times the link was enabled from power-on or from last
         stat clear

0x0B4 0x2D0 IRQ Stat Register 0
  [31:16] IRQ 1 counter
  [15:0]  IRQ 0 counter

0x0B5 0x2D4 IRQ Stat Register 1
  [31:16] IRQ 3 counter
  [15:0]  IRQ 2 counter

0x0B6 0x2D8 IRQ Stat Register 2
  [31:16] IRQ 5 counter
  [15:0]  IRQ 4 counter

0x0B7 0x2DC IRQ Stat Register 3
  [31:16] IRQ 7 counter
  [15:0]  IRQ 6 counter
